摘要
纤维素纳米晶体(CNC)是具有优异力学性能、光学性能和表面化学性能的纳米材料,近年来受到了研究者们的广泛关注.基于CNC的传感器具有对外部环境刺激的单重、双重及多重响应,如湿度、气体、pH、溶剂、温度、光等驱动传感,这使其在信息加密、健康检测、食品、环境监测、储能、可穿戴等领域中显示出巨大的应用潜力.本文对CNC的关键特性进行了简要介绍,并重点分析了基于CNC的多功能传感器的重要应用发展研究机制,最后总结了CNC基传感器材料在制备过程中存在的主要问题和面临的挑战,为提高其性能和功能化创新应用提供参考.
Abstract
Cellulose nanocrystals(CNC)are nanomaterials with excellent mechanical properties,optical properties and surface chemical properties,which have attracted wide attention from researchers in recent years.CNC-based sensors have a single,double and multiple response to external environmental stimuli,such as humidity,gas,pH,solvent,temperature,light and other drive sensing,which makes it in the information encryption,health detection,food,environmental monitoring,energy storage,wearable and other fields show great application potential.In this paper,the key characteristics of CNC are briefly introduced,and the important application development and research mechanism of multi-functional sensors based on CNC are analyzed.Finally,the main problems and challenges in the preparation process of CNC-based sensor materials are summarized,and the reference is provided for improving their performance and functional innovative applications.
