Thin fluoropolymer coating on cotton textile to achieve hydrophobicity
Abstract: We report a simple novel procedure to prepare hydrophobic cotton textiles by admicellar polymerization on the cotton surface. By in situ introducing fluoropolymer on cotton fibers to generate a dual-size surface roughness, followed by hydrophobization with a little amount of fluoromonomer Octafluoropentamethyl methacrylate (OFPM) with short time, normally hydrophilic cotton has been easily turned in to hydrophobic. Hydrophobic cotton textile exhibits a static water contact angle of 135° for a …
