A simple process for fast fabrication of thin films with biomimetic morphological structures from a group of linear homopolymers is developed. Natural evaporation of tetrahydrofuran, chloroform, and hexane-dichloromethane solutions of poly(phenylacetylene)s that contain amino acid and ethylene glycol moieties under ambient conditions instantly produces three-dimensional porous films with structural patterns reminiscent of honeycombs and radiolarian shells. Morphological analysis by optical and electronic microscopy suggests that vesicles of the amphiphilic polymers serve as building blocks in the self-organization to the biomimetic structures.
开发了一种简单的方法，可从一组线性均聚物快速制备具有仿生形态结构的薄膜。在环境条件下，含有氨基酸和乙二醇部分的聚（苯乙炔）的四氢呋喃、氯仿和己烷 - 二氯甲烷溶液自然蒸发，可立即产生具有类似蜂窝和放射虫壳结构图案的三维多孔薄膜。光学和电子显微镜的形态分析表明，两亲性聚合物的囊泡在自组织形成仿生结构中充当构建块。
