摘要: Abstract In this study, we investigated the surface and protein adsorption properties of 316L stainless steels coated with polyvinyl alcohol (PVA) N2-plasma-modified PVA films. The water contact angle steel significantly decreased after coating film owing to abundant hydrophilic functional groups formed on film. signal became more significant N2 plasma modification, leading a further decrease in Electrochemical tests showed that corrosion resistance improved by Bicinchoninic-acid assay results films exhibited lower bovine serum albumin concentrations than neat steel, indicating anticoagulant could be plasma-modified
