“…This is also resonant with hydrophilic behavior of CPO and HPP samples -both submitted to glow discharges, from which these features entail. 26 Moreover, the AFM topography maps for CPO, differently from all other samples, showed in Fig. 1c, and in consonance with friction maps, seemed to present a different surface pattern.…”

“…All sterile samples presented values of WCA between 721 and 881, indicating hydrophilicity characteristics (WCA o 901) which is opposite to the 1021 result of the pristine sample, agreeing with preceding results. 26,35 In particular, an investigation 31 studied the changes that occurred on the surface of the UHMWPE after the plasma-assisted microwave Electron Cyclotron Resonance (ECR) and the effect that these changes cause in relation to the interaction with bone cells. The results obtained indicated the change of the hydrophobic surface (UHMWPE without treatment) to hydrophilic (after treatment).…”

“…Cold plasma oxidation is mentioned as having a long-lasting hydrophilic effect on UHMWPE, 26 and this is possibly incoming from additional groups introduced into the samples' surfaces, seen in FTIR results -that could be credited as to why cell adhesion decreases over time, 26,32,63 a converse phenomenon observed to that on the rest of the samples. Another impacting factor would be the surface texture, especially on the micro-scale, where cell adhesion phenomena occurs -and also AFM results indicate a much rougher surface for CPO samples, leading to a hindering of L929 cell spreading.…”

Ultra-high molecular weight polyethylene (UHMWPE)/epoxy composites with excellent adhesive properties were prepared by forming an interface membrane on the UHMWPE fiber surface. The interface membrane of the UHMWPE fiber and epoxy resin was polymerized by an aldol condensation between polyvinyl alcohol (PVA) and glutaraldehyde. Different surface treatment methods of UHMWPE fibers were optimized and the two-step PVA-glutaraldehyde condensation (Corona-PG-2S) method is the best. The interfacial adhesion between UHMWPE fiber and epoxy resin was enhanced, and the adhesive properties of the composite were improved. X-ray photoelectron spectroscopy (XPS) and energy dispersive spectrum (EDS) results of the fiber treated by Corona-PG-2S shows that the surface oxygen content was up to 25.0 wt %, with an increase of 17.3 wt % compared with the surface oxygen content of unmodified UHMWPE fiber, which indicated that the surface polarity was greatly enhanced. The adhesive properties were improved by improving the polarity of the surface. The peel strength, ultimate cohesive force, tensile strength and flexural strength of the composite treated by Corona-PG-2S were greatly increased to 262.8%, 166.9%, 139.7%, 200.6% compared with those of unmodified samples. The composite prepared by Corona-PG-2S had excellent adhesive properties, demonstrating that the Corona-PG-2S method plays a major role in significantly improving the composite adhesive properties.

In this study, a ultra‐high molecular weight polyethylene (UHMWPE) braided structure was surface modified with low temperature plasma and was coated with cationized gelatin and hyaluronic acid to improve its biocompatibility for the reconstruction of an anterior cruciate ligament (ACL). The ligament was studied for its various mechanical properties. Surface modifications were studied through FESEM. Biological compatibility of the ligament was assessed in accordance to ISO 10993 standard. Tensile strength of the UHMWPE reconstructed ligament ranges between 2628 and 5937 N; maximum tensile strength was attained in 1600 denier 2/2 pattern of triple braided structure along with higher strain at failure of 36.1%. In 1600 denier 2/2 pattern of triple braid structure, the linear stiffness was found to be high at 375 N/mm. Among the developed materials, four braided structures namely as 800 denier 2/2 pattern of double braids and triple braids, 1600 denier 1/1 pattern of double braid and 2/2 pattern of triple braid were found to be mechanically suitable. Specifically, the 1600 denier 2/2 pattern of triple braid having higher mechanical properties was selected for coating. The results of in‐vitro cytotoxicity and genotoxicity confirmed the extract of ACL to non‐toxic and non‐mutant. Furthermore, in‐vivo analysis of the extract and the coated ACL graft proved the ligament to be non‐irritant, non‐sensitizer and also found to promote new tissue formation around the graft. Based on the results, the CG and HA coated ACL graft were concluded to be biocompatible and having considerable potential as an alternate for autograft/allograft.
