摘要
基于纤维素纳米晶体(CNC)的比色传感器可以通过色度感知外部环境的变化,其手性结构和溶胀行为的组合,能迅速响应各种外部环境的刺激。本文主要综述了基于CNC的比色传感器在湿度、压力、气体和有机溶剂外部刺激下颜色的变化情况,并对其未来的发展前景和制备关键点进行了总结。
Colorimetric sensor based on cellulose nanocrystal(CNC)could sense the change of external environment through chromaticity.The combination of its chiral structure and swelling behavior could quickly respond to the stimulation of various external environment.The color change of CNC-based colorimetric sensors under external stimulation of humidity,pressure,gas and organic solvent were summarized in this paper,looking forward to its future development prospects and preparation key points.
