Pcl could form banded spherulites through blending with poly ( bisphenol a - co - decane ) lamellar structures of banded spherulites of poly ( s - caprolactone ) / poly ( vinyl chloride ) ( pcl / pvc ) blends were observed using tapping mode atomic force microscopy ( afm ) 利用原子力显微镜( afm )的轻敲( tapping )模式,系统地研究了聚-己内酯聚氯乙烯共混体系形成的环带球晶表面形貌和片晶结构。

The microcrystalline was same to the direction of electric field . the microcrystalline orientation of the film that was obtained by melting pvdf congealing in the effect of electric field changed along electric field obviously . comparing with the film congealing without electric field their crystalline plate become thick 发现pvdf纤维在电场作用下微观结构变化较大,极化后微晶取向发生较大变化,极化以后微晶变化为沿电场方向取向的厚片状,熔融态的pvdf在电场作用下凝固时变化更明显,与不加电场直接凝固的pvdf膜相比,在电场作用下几乎所有的分子链都沿电场方向取向所以出现有序的片晶结构,而且结构致密。
