摘要:碳纳米管具有优异的力学、电学、热学和光学性能,将功能化碳纳米管与各种聚合物
复合制备水凝胶,可以赋予水凝胶具有良好的导电性能、近红外响应性、pH 响应性以及增
强的力学性能,同时水凝胶也赋予碳纳米管良好的生物相容性。本文综述了聚合物-碳纳米
管复合水凝胶的制备、微观结构、功能特性及形成机理,并探讨了该研究领域所面临的一些
问题及今后的发展方向。

Abstract: Carbon nanotubes show excellent mechanical, electrical, thermal and optical properties
and functional carbon nanotubes could be incorporated into various polymers to prepare
composite hydrogels with good electrical conductivity, near infrared response, pH response as
well as significant improvement in mechanical strength. The hydrogels also fulfill carbon
nanotube good patibility. In this paper, preparation, microstructure, functional properties
and formation mechanism of polymer-carbon posite hydrogels were summarized,
and some of the problems faced in the field of research and the future direction of development
were also explored.
Keywords: polymer functional material; carbon nanotube; hydrogel; smart responsibility
