Preparation and Properties of Superhydrophobic Anticorrosion Surface Modification Paper
The copolymerization of azide monomer and fluorinated monomer was achieved by visible light facilitated atom transfer radical polymerization(ATRP),and the perfluorooctyl azide copolymer was obtained.This polymer was applied to paper surface modification,and the superhydrophobic anticorrosion paper was made.The effects of monomer types,monomer proportion and polymer molecular weight on the superhydrophobic anticorrosion were studied.In addition,the surface microstructure of the modified paper,the connection between the polymer and the paper were characterized.And the principle of superhydrophobic anticorrosion of the modified paper was explained.When the molar ratio of phenyl-4-azide methacrylate to perfluorooctyl methacrylate was 1∶4,the paper modified with perfluorooctyl azide copolymer-80 showed strong hydrophobicity,and water contact angle reached 165°.The modified paper maintained no significant change in strong acid(pH=1)or strong base(pH=13)environment for 72 h.The polymer shows a good prospect in the application of water resistance,acid and alkali resistance.
