中文摘要：

通过测定水和甘油在PS—b—PMTFPS／PS共混聚合物膜表面接触角的变化，发现在聚合物中引入少量含氟聚硅氧烷链段可以明显提高聚合物膜的憎水、憎油性，当含氟链段含量仅0．39％时，表面张力达到15．69×10^-3N／m，显示出明显的低表面能特征。而热处理能有效地增强这一效果，在含氟链段含量较低时尤其明显。

英文摘要：

By measuring the contact angle of water and glycerol on the polymer films of the blends of polystyrene-b-polymethytrifluoropropylsiloxane diblock copolymers and polystyrene, good water and oil repellency was exhibited due to the introduction of fluorinated block in polymers. The annealing treatment could further improve the effect of water and oil repellency, particularly at low fluorinated chain content. When the fluorinated chain content was only 0. 39%in polymer blends, the surface tension of the film approached 15. 69× 10^-3 N/m, which suggesting the characteristics of low surface energy.
