Preparation and Hydrophobicity of Silanized Fluoro-Polyacrylate Emulsion
摘要
Abstract
A novel silanized fluoro-polyacrylate emulsion (FLHDV) was prepared by copolymerization of dodecafluoroheptyl methacrylate, lauryl methacrylate, 2-hydroxypropyl acrylate, dimethylaminoethyl methacrylate and vinyltrioxethylsiloxane with (NH4)2S2O8 as the water soluble initiator and cationic/nonionic surfactants as the mixed emulsifier.The structure and the film morphology of the prepared FLHDV and the chemical composition and the hydrophobicity of the FLHDV film surface was characterized by means of FTIR, SEM, XPS and the contact angle determination instrument.The results showed that the smooth FLHDV film could form on the terylene surface.The silanization could enhance the degree of crosslinking of the prepared FLHDV and its attachment to the terylene, which conferred excellent water repellency on the treated terylene.Consequently, the terylene changed from hydrophilicity to hydrophobicity, and its water static contact angle on the treated terylene surface reached 142.5°.关键词
