改进聚乙烯（PE）薄膜透水汽性的研究

Study on the Improvement of Aqueous Vapour Permeability of Polyethylene Film

本文研究了ＰＥ薄膜透水汽性改进的方法，得到一些有意义的结果：（１）在ＰＥ膜涂上极性膜（不论是涂在膜内表面或外表面）后，其透水量均比单纯薄膜的为大。（２）ＰＥ膜涂上极性高聚物薄层后透水量随其膜总厚度而变化，且在一定厚度时皆出现一个极大值。

Abstract The improvement of aqueous vapour permeability of polyethylene film was investigated and some results were obtained as follows: (1)The permeability of PE film coated with some polarizing polymers either on its inner or outer suface was better than that of pure PE flm.(2)The permeability of PE film coated with polarizing polymer changd with the total thickness of the film. and always reached a maximum at certain thicknesses.
