用阴离子、非离子和阳离子乳化剂制备了聚甲基丙烯酸甲酯-丙烯酸丁酯乳液,非离子乳化剂制备了聚甲基丙烯酸六氟丁酯乳液。将含氟乳液与不含氟乳液共混,并室温成膜。采用AFM、SEM-EDS、接触角仪比较了上述3种共混膜的结构和性能。结果表明不含氟乳液乳化剂为阴离子或非离子时,更有利于形成两面异性,具备优异的性能。 Poly (methyl methacrylate) - butyl acrylate emulsion was prepared with anionic, nonionic and cationic emulsifiers. Poly (hexafluorobutyl methacrylate) emulsion was prepared with nonionic emulsifier. The fluorinated emulsion and non-fluorinated emulsion were blended and film-formed at room temperature. The structure and properties of the three blend membranes were compared by AFM, SEM-EDS and contact angle meter. The results show that non-fluorinated emulsion emulsifier anionic or non-ionic, more conducive to the formation of the opposite, with excellent performance.
