固化剂对聚硅氧烷涂层疏水性的影响

The Effect of Some Kinds of Curing Agent on the Hydrophobicity of Hydroxyl-Terminated Polydimethelsiloxane Coatings

本文研究了三种固化剂对聚二甲基硅氧烷涂层疏水性的影响。在固化剂用量方面,发现存在共同规律,即在固化剂某一用量范围内涂层疏水性最强,分析讨论了这种规律形成的原因。在固化剂结构方面,证明固化剂中含有规则排列的甲基有利于增强涂层的疏水性。

The effect of some kinds of curing agent on the hydrophobicity of hydroxyl-terminated polydimethelsiloxane coatings was studied. It was discovered that the hydrophobic ity of coatings increases first with the adding of curing agent, then decreases; and that the curing agent con taining methyl improves the hydrophob ic ity of coatings.
