Effect of external field on the lamellar crystalline structure and properties of poly(4‐methyl‐1‐pentene) casting film

ABSTRACT In this work, lamellae structures of poly(4‐methyl‐1‐pentene) casting films with different draw ratios and properties of corresponding stretched membranes were discussed. The crystalline structure was quantitatively analyzed in terms of crystallinity, long period, crystalline orientation, a...

Description
Summary:ABSTRACT In this work, lamellae structures of poly(4‐methyl‐1‐pentene) casting films with different draw ratios and properties of corresponding stretched membranes were discussed. The crystalline structure was quantitatively analyzed in terms of crystallinity, long period, crystalline orientation, and lamellae lateral dimension, which were largely influenced by the draw ratio. Apparently, as draw ratio increased, the elapsed time of samples declined rapidly and porosity showed an upward tendency. In this article, these results can be used to predict the relationship between properties of casting films (such as orientation, lamellar structure, and elastic recovery) and properties of stretched membrane (average pore size, permeability, and porosity). © 2018 Wiley Periodicals, Inc.
