Abstract

Cationic water-based polyurethane(CWPU) was synthesized to explore aloe-emodin modifies to obtain CWPU materials with better comprehensive performance. It provides a simple way to synthesize antibacterial waterborne polyurethane, which is to introduce the end-blocking group of herbal extracts into the structure. It contains synergistic antibacterial effect of herbal antibacterial and quaternary ammonium ion on Escherichia coli. It makes the material resist the erosion of bacterial, and increase the service life of materials. When the pH value of the environment changes, the UV absorbance of the aloe-emodin modified cationic water-based polyurethane(AE-CWPU) also changes. Therefore, within a certain detection range, AE-CWPU has great applications in the field of smart response materials. The modified thermodynamic properties have been improved, and the mechanical properties basically maintained the maximum stress, and the elongation at break was reduced.

基于芦荟大黄素改性的抗菌碱敏阳离子水性聚氨酯。

以芦荟大黄素为改性剂，合成了阳离子水性聚氨酯（CWPU），得到了综合性能较好的CWPU材料。它提供了一种合成抗菌水性聚氨酯的简单方法，即在结构中引入草药提取物的末端封闭基团。它含有草药抗菌剂和季铵离子对大肠杆菌的协同抗菌作用。它使材料能够抵抗细菌的侵蚀，提高材料的使用寿命。当环境pH值变化时，芦荟大黄素改性阳离子水性聚氨酯（AE-CWPU）的紫外吸光度也发生变化。因此，在一定的检测范围内，AE-CWPU在智能响应材料领域有很大的应用。改性后的热力学性能得到改善，力学性能基本保持最大应力，断裂伸长率降低。
