WebSep 17, 2024 · It can be biologically inert or biodegradable. Biocompatibility, defined as the ability of a substance to perform specific functions while eliciting an acceptable host response , is one of the most important characteristics of biological materials . As a result, bio-inert materials such as titanium (Ti), stainless steel, nickel (Ni) alloys, and ... WebPoly(tetrafluoroethylene) (PTFE) is a very inert material due to the large fluorine atoms protecting the hydrocarbon backbone, its high molecular mass, and high crystallinity. It has a low friction coefficient, and one of the lowest critical surface tensions of any polymer. The hydrophobicity of PTFE is evident from its high water contact angle ...

WebTitanium naturally passivates, forming an oxide film that becomes heterogeneous and polarized as a function of exposure time to bodily environments. This leads to the increased adsorption of hydroxyl groups, lipoproteins, and glycolipids over time. The adsorption of these compounds changes how the material interacts with the body and can improve … WebFeb 25, 2024 · Ti is widely used as a material for orthopedic implants. As rapid and effective osseointegration is a key factor for the successful application of implants, biologically inert Ti materials start to show inherent limitations, such as poor surface cell adhesion, bioactivity, and bone-growth-inducing capabilities. Surface modification can be an …
