Abstract

The crystal morphologies of poly(ε-caprolactone) solvent-cast films in the absence and presence of multi-walled carbon nanotubes were observed using polarized optical microscopy. The experimental results indicated ring-banded spherulites containing polygonal holes could be induced by dewetting on the surface of the substrate. The polymer crystals assembled into a hierarchical structure induced by the change of the crystallization temperature. Further it was found that the loading of nanotubes into polymer matrix could change the ring-banded structure in the spherulites.

聚（ε-己内酯）和聚（ε-己内酯）/多壁碳纳米管溶剂铸造薄膜中的奇特晶体结构

摘要利用偏振光学显微镜观察了无多壁碳纳米管和有多壁碳纳米管存在时的聚(ε-己内酯)溶剂浇铸膜的晶体形态。实验结果表明，基底表面的脱水作用可诱导出含有多边形孔洞的环带球晶。聚合物晶体在结晶温度变化的诱导下形成了分层结构。研究还发现，在聚合物基质中加入纳米管可改变球状晶体的环带结构。

期刊介绍： Polymer Science, Series A is a journal published in collaboration with the Russian Academy of Sciences. Series A includes experimental and theoretical papers and reviews devoted to physicochemical studies of the structure and properties of polymers (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed. Online submission via Internet to the Series A, B, and C is available at http://polymsci.ru.
