生物质基导电水凝胶的研究进展

Advances in Research of Biomass-based Conductive Hydrogels

随着石油危机日趋严重与“绿色发展”观念持续推进,生物质材料凭借其可再生、来源丰富、可生物降解、生物相容性好等诸多优势已成为众多领域的研究热点。生物质基导电水凝胶(Biomass-based conductive hydrogels,BCHs)是以生物质为原料制备的具有导电性质的水凝胶,具有生物质材料良好的生物相容性和生物降解性等本体性能,同时具有水凝胶的柔软特性和导电功能材料的电化学性能。本文首先根据导电原理的不同,将BCHs划分为离子导电、电子导电、离子-电子协同导电三个类型,接着介绍了基于BCHs的柔性可穿戴设备、超级电容器、发电机、智能机器人、组织工程等领域的最新应用研究,最后结合目前研究现状,对BCHs的应用前景和发展趋势进行展望。

With the increasing severity of the oil crisis and the continuous promotion of the concept of‘green development’,biomass materials have become the research hotspot in many fields by virtue of their renewable,abundant sources,biodegradability,and good biocompatibility.Biomass-based conductive hydrogels(BCHs)are biomass-based hydrogels with conductive property,which have the ontological properties of biomass materials such as good biocompatibility and biodegradability,as well as the soft property of hydrogels and electrochemical properties of conductive materials.In this paper,firstly,BCHs are classified into three types ion-conducting,electron-conducting,and ion-electron synergistic conducting,according to the different principles of conducting electricity.Then,the latest researches on the application of BCHs flexible wearable devices,supercapacitors,generators,intelligent robots,tissue engineering,and other fields are introduced.Finally,the application prospect and development trend of BCHs are prospected with the current research status.
