Preparation and Water/Oil Repellency Properties of Waterborne Cationic Perfluorinated Polyacrylate

Abstract:

A series of waterborne cationic perfluorinated polyacrylate (WCFPA) were prepared by the reaction of styrene (St), methacrylatoethyl trimethyl ammonium chloride (DMC), butyl acrylate (BA), octadecyl acrylate (ODA) and 2-(perfluorooctyl)ethyl acrylate (FEA) by soap-free emulsion copolymerization and then the films of the WCFPA were prepared. Their structure and water/oil repellency properties, such as surface property, water and chemical resistance of their membrane were characterized by fourier transform infared spectrometer (FT-IR), interfacial tension instrument (IT), contact angle (CA) and spot test. The results reveal that WCFPA was endowed with low surface energy of its film. It was also found that the fluorinated polyacrylate had outstanding water and chemical resistance. Increasing the FEA amount in the emulsion was as sociated with larger contact angle and better water and oil repellency.
