聚己二酸对苯二甲酸丁二酯泡沫泡孔结构和性能研究

Research on Structure and Properties of PBAT Foam

近年来,生物可降解材料一直是研究的热点,其也成为了运动鞋材可持续发展的选择之一。本文通过超临界物理发泡技术制备生物可降解聚合物聚己二酸对苯二甲酸丁二酯(PBAT)泡沫材料,探索了二氧化碳在材料中的溶解特性,筛选出最佳的发泡压力和温度,并研究了发泡材料的密度和回弹性能的关系。最终开发出了落球回弹率高于50%,密度为0.14 g/cm^(3)的PBAT泡沫材料,并制作成了生物可降解跑鞋中底及部件。

Biodegradable materials have been a research hotspot recently,which has also become one of options in athletic shoe sustainable materials.Biodegradable polymer PBAT foam was prepared by supercritical fluid foaming technology,the solubility characteristics of CO_(2) in the PBAT material were explored,the best saturation pressure and temperature were screened,and the relationship between the density and the elastic of the foam material was studied.Finally,PBAT foam with a rebound of more than 50%and a density of 0.14 g/cm^(3) was developed and made into biodegradable running shoe midsoles and parts.
