摘要: 通过乳液聚合反应制得聚苯乙烯(PS)乳液,将PS按照不同的体积比和聚四氟乙烯(PTFE)乳液混合得到杂化乳液。使用浸渍提拉法制备薄膜,在80 ℃烘干,330 ℃和420 ℃进行热处理,当PS与PTFE两种乳液体积比为0.6时得到超疏水薄膜,薄膜与水的接触角最高可达152.4°。使用场发射电子显微镜(FESEM)、Jupiter同步热分析仪和傅里叶红外光谱仪(FTIR)对薄膜的表面形貌和化学组成进行了表征。

Abstract: Polystyrene(PS)emulsion was obtained from an emulsion polymerization process,and then the as-prepared emulsion was added into polytetrafluoroethylene(PTFE)emulsion with different volume ratio to form hybrid emulsion. The films were prepared by dip-withdrawing method. While the volume ratio of PS emulsion to PTFE was 0.6,after being dried at 80 ℃ and heat-treated at 330 ℃ and 420 ℃,the films exhibited a superhydrophobic property. The water contact angle of the films could reach to 152.4°. Field emission scanning electron microscopy(FESEM),Jupiter simultaneous thermal analyzer and Fourier transform infrared spectrophotometer(FTIR)were applied to analyze the morphology and the structure of the surface.

Key words: superhydrophobic, polytetrafluoroethylene emulsion, polystyrene emulsion, emulsion hybrid, contact angle
