Preparation and properties of amphiphilic organic-inorganic hybrid modified silicone antifouling materials
Polydimethysiloxane(PDMS)material has poor mechanical strength and water resistance,and its anti-fouling performance depends on seawater erosion,and its static anti-fouling effect is relatively poor.In this paper,amphiphilic prepolymers were prepared by prepolymerization of polyethylene glycol methyl orth osilicate methacrylate,dodecafluoroheptyl methacrylate and 3-mercaptopropyltriethoxysilane.In addition,y-methacryloxypropyl-trimethoxysilane hydrophobically modified SiO2 was prepared by sol-gel method using tetraethyl orthosilicate as raw material.Then,it was mixed with PDMS and solidified to form an organic-inorganic cross-linked network,which not only promoted the self-enrichment effect of amphiphilic prepolymer on the coating surface,reduced the adhesion ability of marine organisms such as bacteria and diatoms and large fouling organisms,but also improved the static antifouling ability,water resistance and adhesion strength of the material to the substrate material.
