Electrodepositing salicylate modified PHEMA on stainless steel surface for hemocompatibility
Source abstract
Abstract
Using electrodeposition of poly(hydroxyethylmethacrylate)–glycidyl methacrylate–salicylic acid (PHEMA-GMA-SA) in this study, the surface of stainless steel was modified by PHEMA to improve its surface properties of corrosion resistance and hemocompatibility for biomedical applications. Electropolymerisable SA was introduced on PHEMA-GMA by ring opening reaction of the epoxy group of GMA. Poly(hydroxyethylmethacrylate)–glycidyl methacrylate was synthesised by precipitation copolymerisation of HEMA and GMA in ethyl acetate. Ultraviolet spectrum was applied for calculating the degree of substitution of SA in the copolymer. Structure of the electrodeposited layer was verified by Fourier transform infrared. Polarisation curves and electrochemical impedance spectroscopy technologies were used to estimate the corrosion resistance of PHEMA modified stainless steel. The hemocompatibility of PHEMA modified stainless steel was determined by bovine serum albumin adsorption and platelet adhesion.
