The antifouling performance of biomimetic fish slime-like PVA/PAAm hydrogels modified coating in marine

EasyChair Preprint 436

Abstract

In this paper, a fish slime-like coating modified by poly vinyl alcohol/polyacrylamide (PVA/PAAm) hydrogel which is the semi-interpenetrating network polymer was designed. A physical blending method loading PVA/PAAm hydrogels powder into the organic silicon resin was employed to prepare the coating. The oil-resistance of the coating was performed by time-sequence images of washing dyed beef tallow stain away. The results showed that the PVA/PAAm hydrogels modified coating had the greater ability of stain removal. The biomass of a marine microalgae species, Nitzschia closterium and f. minutissima attached on the coating were investigated using UV-Visible Spectrophotometer (UV) and Scanning electron microscopy (SEM). The results showed that the microalgaes showed a significantly lower numbers attached on PVA/PAAm hydrogels modified coating in comparison  with on the organic silicon coating.
