Morphology control of semi-crystalline polymers with supramolecular additives (B04)

在前人对聚丙烯研究成果的基础上，合成了适合于非晶态聚苯乙烯和半晶态聚对苯二甲酸丁二酯泡沫成核剂的超分子助剂。重点评价了聚合物熔体中溶解发泡剂与发泡过程中不同步骤形成的超分子纳米物体之间的相互作用。结构-性能关系的发展，从所得的微细胞和纳米泡沫。此外，本文还探讨了新发现的铁电畴纳米物体的中尺度结构及其潜在的应用。

Based on the results achieved on polypropylene in the previous period, tailored supramolecular additives are synthesized as nucleating agents for amorphous polystyrene and semi-crystalline polybutylene terephthalate foams. One focus is on the evaluation of the interaction between dissolved blowing agent in the polymer melt and the supramolecular nano-objects which are formed in the different steps of the foaming process. Structure-property relationships are developed from the resulting micro- and nanocellular foams. Furthermore, the newly discovered, mesoscale structuring of the nano-objects in ferroelectric domains, as well as their potential applications, are explored.
