聚二甲基硅氧烷－氯磺化聚乙烯共混涂膜表面润湿性与表面结构的研究

STUDY ON THE HYDROPHOBICITY AND SURFACE STRUCTURE OF BLEND COATINGS OF POLYDIMETHYLSILOXANE-CHLOROSULFONATE POLYETHYLENE

研究了α，ω－二羟基聚二甲基硅氧烷（ＨＴＰＤＭＳ）－氯磺化聚乙烯（ＣＳＰ）非均相共混涂膜表面润湿性与表面结构的关系，发现膜表面疏水性随ＣＳＰ含量增加而出现突变点．ＸＰＳ分析证明，这是由于氯元素在表面含量呈突变性。阐明均一的疏水性共混涂膜形成的条件．

The surface hydrophobicity and structure of blend coatings of hydroxyl terminated polydimethylsiloxane (PDMS) and chlorosulfonated polyethylene(CSP) are studied. There is a knee point at the curve of the hydrophobicity of the coatings-CSP percent. By XPS,it is demonstrated that the nature of this phenomenon is the function of chlorine-content at the coatings surfaces. The conditions in.which the uniform hydrophobic blend coatings form are described.
