摘要
纤维素纳米晶(CNC)是从天然植物纤维原料中提取的棒状纳米材料,长度为几百纳米,直径为5~50 nm,因其具有天然绿色、生物降解性、生物相容性,高比表面积、反应活性较大等特性,受到国内外学者的广泛关注。本文综述了CNC的制备和改性方法,概述了现有的CNC表征方法,介绍了CNC材料在食品、生物医药、环保、光电能源等领域的应用,并对其未来发展趋势进行了展望,旨在为促进纤维素纳米晶资源的开发利用提供理论参考。
Cellulose nanocrystals(CNC)are rod-like nanomaterials extracted from natural plant fibers,with a length of several hundred nanometers and a width of 5~50 nm.Because it is natural green,biodegradable,biocompatible with high specific surface area and great reactivity,CNC has been widely investigated by researchers.In this review,the preparation and modification methods of CNC are summarized,and the characterization methods of CNC are also introduced.Furthermore,the applications of CNC materials in biomedicine,photoelectric energy,environmental protection,food and other fields are also summarized,and its future development trend is prospected.This review may provide theoretical references for the development and utilization of cellulose nanocrystals.
