Corrosion Behaviour and Fibrinogen Adsorptive Interaction of SS316L Surfaces Covered with Ethylene Glycol Plasma Polymer-coated Ti Nanoparticles

A novel plasma treatment involving the deposition of ethylene glycol plasma polymer-coated titanium nanoparticles on a 316L stainless steel surface is presented. The surface properties of SS316L modi!ed with these coated nanoparticles were compared to untreated SS316L. The deposition of ethylene glycol plasma polymer-coated nanoparticles confers properties to the surface making it more biocompatible, which is bene!cial in applications of SS316L as a blood-contacting implant (e.g. vascular stents, heart valves). These properties include increased hydrophilicity and general corrosion resistance of the surface, and reduced substrate-dependent denaturation of adsorbed protein fibrinogen.
