羟乙基纤维素基载银复合气凝胶的制备及性能

The Preparation and Antibacterial Properties of Aerogel Composites Based on Hydroxyethyl Cellulose and Silver Nanoparticles

针对生活用水、工业用水细菌含量不达标问题,本文以羟乙基纤维素(HEC)、纳米银溶液为原料,聚乙烯吡咯烷酮(PVP)为保护剂制备了一种基于羟乙基纤维素的复合气凝胶抗菌过滤材料(HEC-PVP)。研究了HEC-PVP复合气凝胶的抗菌性能,探讨了HEC-PVP复合气凝胶的制备工艺,同时分析了较优工艺条件下制备的HEC-PVP复合气凝胶的力学性能、水中结构稳定性、抗菌性能等。

In order to overcome the problem that the bacterial content of domestic and industrial water is not up to standard, a hydroxyethyl cellulose（HEC）-polyvinyl pyrrolidone（PVP） composite aerogel was prepared by using HEC and nano silver solution as raw materials and PVP as protective agent. The antibacterial properties and preparation process of the HEC-PVP composite were researched. The results indicate that the prepared HEC-PVP aerogel has excellent structural stability, mechanical properties and antibacterial properties.
