  • Tribological Analysis on Hybrid PEEK-Based Polymer Composites for Prosthetic Implant Applications
    Sathishkumar Sankar, Prasun Chakraborti, Chandradass Jeyaseelan, Jawahar Paulraj
    Journal of Tribology, 2026
    Assessing the tribological nature of biomaterials is a prominent task before using them as an implant material. The current investigation deals with the high-performance polyether ether ketone (PEEK) polymer with the hybrid reinforcements of graphene oxide (GO) and hydroxyapatite (HA) with various concentrations of 0.5, 1.0, 1.5 wt% and 10, 20, 30 wt%, respectively. The wear study was performed using a linear reciprocating tribometer under dry conditions. The testing parameters significantly varied (load: 50 N, 90 N, 150 N and stroke length: 10, 13, 20 mm) to measure the material's dynamic tribological attributes. Fourier transform infrared spectroscopy characterized the samples' chemical bonds and functional groups, and X-ray diffraction was used to identify the crystallographic nature. Microstructure and wear scar were assessed by optical and field emission scanning electron microscopy, respectively, and the elemental composition was evaluated by energy dispersive X-ray spectroscopy. The results demonstrated that a lower coefficient of friction (0.16901) was obtained on minimum GO and HA-concentrated samples at lower load (50 N) and minimal stroke length (10 mm). Similarly, a lower wear-rate (1.691 × 10−6 mm3/N m) was obtained on minimum GO and HA-concentrated samples at lower load (50 N) and maximum stroke length (20 mm). Comparatively, the reinforcement plays a vital role in the structure of the tribological behavior of the hybrid PEEK composites. Electrostatic interaction between GO and HA and π–π stacking interaction between GO and PEEK make it an effective scaffold material for various orthopedic applications.

  • Numerical Investigation of Polymer-based Biomaterials for Artificial Hip Joint with Diverse Boundary Conditions
    S. Sathishkumar, P. Jawahar, Prasun Chakraborti
    Recent Patents on Engineering, 2025
    Background: Hip suffering is a serious concern for human health, which may be caused by arthritis, accidents, and childhood disorders; hence, man-made joints are the only option for restoring the function of natural hips and ensuring a comfortable life. To design an effective hip joint is a challenging task; there are myriads of novel designs continuously patented over the last two decades. Methods: The finite element approach was utilized in this extensive investigation to assess selfmated polymer-based biomaterials (PTFE, UHMWPE, and PEEK) with different boundary conditions. The numerical analysis was performed to find the stress intensity and deflection of the femoral head and the acetabular components; the evaluation was done critically with a 10-node quadratic tetrahedron element and different mesh intensities. Results: The detailed outcome showcases that the bare PEEK mated GO-PEEK has good load resistance and is affected by minimum stress and deflection, which is quantified at 20.89% less than the PTFE with GO-PEEK (M3) combination. This stress and deflection are quite higher than those of metal implants (Ti6Al4V) but comparatively more prominent materials for human cortical bone. Conclusion: This investigation proved the polymer-on-polymer combination effectively eliminates stress shielding and metal ion emission, reducing revision surgery and elevating implant longevity. Therefore, it was identified that PEEK-based polymer composites are the best-suited alternative substance for hip repair applications.
  • Mechanical and tribological assessment of PEEK and PEEK based polymer composites for artificial hip joints
    Sankar Sathishkumar, Jawahar Paulraj, Prasun Chakraborti, Jeyaseelan Chandradass, Subrata Kumar Ghosh
    International Journal of Materials Research, 2024
    Human hip failure remains a significant issue, and constructing artificial joints is imperative for affected individuals. This study examined the mechanical and wear behavior of polyether ether ketone (PEEK) polymers, including bare PEEK (BP), HA (Hydroxyapatite)-infused PEEK (HA-PEEK), and GO (Graphene oxide)-infused HA-PEEK (GO-HA-PEEK). The samples were prepared using compression molding, and wear characteristics were evaluated using a linear reciprocating tribo-tester against a stainless-steel counterface under a load 50 N, frequency 5 Hz, stroke length 20 mm, and time 30 min. The 10 % w/w HA inclusions slightly elevate the PEEK’s tensile strength from 29.85 ± 1.11 MPa (BP) to 34.23 ± 1.09 MPa, and the 0.5 % w/w GO with 10 % w/w HA encapsulations have significantly improved tensile properties (65.10 ± 1.12 MPa), which is 2.2 fold higher than the BP. However, the attained impact properties fall below the satisfactory level. Coefficient of friction and wear rate are significantly reduced. The wear rate reduced from 3.39 × 10−6 mm3 N−1 m−1 (BP) to 2.54 × 10−6 mm3 N−1 m−1 on HA-PEEK, and more than two times reduction (1.69 × 10−6 mm3 N−1 m−1) with 0.5 % w/w GO incorporating HA-PEEK. The results show that the reinforcements significantly reduced wear and improved the mechanical strength of PEEK polymers. Unlike BP and HA with lowered impact resistance, GO integrated HA-PEEK exhibited outstanding mechanical and wear performance. Therefore, HA and GO-infused PEEKs are suitable alternatives for hip repair applications.

    Tribo Behaviors of Biomaterials and their Applications Fundamentals Recent Advancements and Future Trends, 2024
    Bioimplants took on an essential role for providing a comfortable life for those who have suffered the loss of organs by accident, diseases, and other circumstances. Wear debris emission is one of the most challenging problems because it provokes pathological action on the hosting body, eventually leading to implant failure. So great attention should be paid by the researchers during implant material selection. Generally implants are constantly interacting with human blood, proteins, water, and cell surfaces; hence their emitted wear debris easily reacted with these biomolecules and provokes severe consequences, such as inflammation, tissue necrosis, osteolysis, bone resorption, and aseptic loosening. Initially, with inflammation, the implant loses its effectiveness and eventually leads to degradation of the stem cells, like osteolysis, and may disturb blood circulation in the areas and ultimately lead to fractures and aseptic loosening. In this ambiance, the victim requires immediately revision surgery preserve motilities. It will be emphasized that, before implantation, structured wear studies are most essential for prolonged implant performance. In this chapter, we illustrated the wear quantification methods, a list of wear mechanisms, the tribological nature of various biomaterials, followed by the physiological implication on wear debris and strategies for making robust wear-resistant implants. We anticipate that this chapter will be beneficial to future researchers in their attempt at fascinating wear-resistant biomaterial for prosthetic hip joints. This will allow us to create a more pleasant life for those who are afflicted.

    Tribo Behaviors of Biomaterials and their Applications Fundamentals Recent Advancements and Future Trends, 2024
    Friction and wear are intertwined phenomena, most noticeably for artificial implants due to their continuous interaction with the human body. Surface coating is one of the eminent strategies to elevate the performance and durability of implants by improving their wear resistance, friction coefficient, and corrosion resistance. This chapter covers different types of coatings, such as metallic, ceramic, and polymer coatings, and coating techniques, including physical vapor deposition, chemical vapor deposition, and electrochemical deposition. The study emphasizes surface coatings optimization to achieve the desired tribological performances. Additionally, the authors discuss the challenges and opportunities associated with surface coating technology for bioimplants, highlighting the importance of advanced coating techniques and materials development to improve tribological behavior with an extended lifespan. We look forward to this chapter being more beneficial for upcoming biomechanical researchers, and it may lead to the discovery of new surface coating technologies to improve bioimplants’ surface behaviors.
  • Comprehensive Review on Biomaterials and Their Inherent Behaviors for Hip Repair Applications
    S. Sathishkumar, Jawahar Paulraj, Prasun Chakraborti, Muthusivaramapandian Muthuraj
    ACS Applied Bio Materials, 2023
    Developing biomaterials for hip prostheses is challenging and requires dedicated attention from researchers. Hip replacement is an inevitable and remarkable orthopedic therapy for enhancing the quality of patient life for those who have arthritis as well as trauma. Generally, five types of hip replacement procedures are successfully performed in the current medical market: total hip replacements, hip resurfacing, hemiarthroplasty, bipolar, and dual mobility systems. The average life span of artificial hip joints is about 15 years, and several studies have been conducted over the last 60 years to improve the performance and thereby increase the lifespan of artificial hip joints. Present-day prosthetic hip joints are linked to the wide availability of biomaterials. Metals, ceramics, and polymers are some of the most promising types of biomaterials; nevertheless, each biomaterial has advantages and disadvantages. Metals and ceramics fail in most applications owing to stress shielding and the emission of wear debris; ongoing research is being carried out to find a remedy to these unfavorable responses. Recent research found that polymers and composites based on polymers are significant alternative materials for artificial joints. With growing research and several biomaterials, recent reviews lag in effectively addressing hip implant materials' individual mechanical, tribological, and physiological behaviors. This Review comprehensively investigates the historical evolution of artificial hip replacement procedures and related biomaterials' mechanical, tribological, and biological characteristics. In addition, the most recent advances are also discussed to stimulate and guide future researchers as they seek more effective methods and synthesis of innovative biomaterials for hip arthroplasty application.
