Abstract

Abstract:

The fluorine modified acrylate emulsion polymerization was performed using sodium dodecyl sulfate(SDS) and octylphenyl polyoxyethylene ether(OP-10) as complex emulsifiers, 2-(perfluorohexyl) ethylmethacrylate(PFM) as the fluorinated acrylate monomer, and potassium persulfate(KPS) as the initiator. Spiropyran was physically blended with the emulsion to obtain a photochromic fluorinated acrylate emulsion. The effects of the mass ratio of methyl methacrylate(MMA) to butyl acrylate(BA) monomers, and the amount of hydroxyspiropyran(SPOH) on the polymerization and the properties of the latex films were studied by means of various spectroscopic methods. The results show that the contact angle and thermal stability of the fluorinated polyacrylate are improved. The film presents good photochromic properties with addition of 1.25%(mass fraction) spiropyran.

Key words: emulsion polymerization, photochromic, fluorinated acrylate, spiropyran
