埃洛石纳米管/壳聚糖复合材料的研究进展

摘要

The recent applications and developments of halloysite/chitosan composites are reviewed,and the preparation,properties and the present application situation of composites are also discussed,which has significance for the research.Then several kinds of preparation methods are introduced,such as solution blending method,solvent casting method,emulsion crosslinking method,chemical precipitation method,electrochemical deposition method,electrostatic spinning method and sol-gel method.This composite has been stumed and applied widely in governance of water pollution,biomedical materials and material research.In the end,the study and prospects of composite materials are presented.%首先对国内外埃洛石/壳聚糖复合材料的研究现状进行分析,然后介绍了埃洛石纳米管与壳聚糖的基本特点和应用情况.通过化学的视角综述了几种埃洛石/壳聚糖复合材料的制备方法,主要包括溶液共混法、溶剂浇铸法、乳化交联法、化学沉淀法、电化学沉积法、静电纺丝法、溶胶-凝胶法.同时阐述了所制得的复合材料的几种特性,发现其具有机械性能、生物相容性、无毒性和吸附性的优点,使得埃洛石纳米管/壳聚糖复合材料在生物医药、作为吸附剂治理水污染方面的应用有着广泛前景.最后,对该复合材料未来的研究发展予以展望.
