Application of Inorganic Fillers in Modified Amphiphilic Hydrogel Antifouling Materials
Hydrogel antifouling materials have become a research hotspot in the field of marine antifouling due to their environmental properties.However,their lack of adhesion and mechanical properties is still the key technology limiting their practical application.In this study,on the basis of the oil structure unit to increase the adhesion of amphiphilic hydrogel,the introduction of Al2O3,TiO2,montmorillonite and kaolin through physical blending to give more adhesion mechanism of amphiphilic hydrogel coating and investigate their effects on other properties of hydrogel coating.It was found that with the introduction of inorganic fillers and the increase of content,the adhesion performance of hydrogel coating was greatly improved,and the non-falling time of static foam plate and dynamic stroke was increased by 6 times and 2.5 times,respectively.Among them,TiO2 and kaolin can significantly enhance the stress of the hydrogel coating.Although the addition of inorganic fillers decreased the ability of amphiphilic hydrogel coating to inhibit the adsorption of bovine serum protein and diamondiella parvum,it still showed considerable anti-fouling ability in the test of actual sea hanging plate,and has certain practical application value.This study provides some references for exploring the effect of inorganic fillers on the properties of hydrogel coating,and provides a strategy for improving the adhesion and mechanical properties of amphiphilic hydrogel coating.
