| 摘 要： | 依循“后排前推法”的构思,进行聚氨酯改性的分子设计,获得良好的效果。用极性聚合物的单体对聚氨酯接枝共聚,而后扩链交联成为互贯聚合物网络,提高了水的湿润能力和均匀传递补膜的作用。液体和固体的界面张力和它们的接触角θ成正比的关系,能更直观地估价液体对固体表面的润湿程度。

| Abstract: | According to the supposition of BACKTRACKING, better results can be obtained through doing molecular design of polyurethane modification, The wetting capacity of water to it and the function of uniform transition water-film are increased in using the graft copolymerization of the monomer of polar polymers to polyurethane and then extending and networking into an interpenetrating polymer network. Also because of the directly proportional relation between the interfacial tension of liquil and solid and their contact angle 0, the wetting degree of liquid to solid surface can be more djrect-viewingly estimated. |
