Cellulose Nanocrystals Based Photonic Films:Innovative Materials with Multiple Properties and Their Application Prospects
Advanced technologies for sustainable energy storage and conversion,and light resources management are research hotspots around the world.Cellulose has attracted great interest due to its rich natural sources and excellent properties.This paper reviews the latest research progress on cellulose nanocrystal(CNC)-based films,focusing on the preparation and application of CNC photonic films.CNC obtained by cellulose hydrolysis has many characteristics,such as biodegradable,high surface area,low cost,good mechanical property,surface functionality,and chiral nematic self-assembly.Specifically,this review systematically compares different methods(e.g.,acid hydrolysis,mechanical,oxidative hydrolysis,and enzymatic hydrolysis)for producing CNC and the shortcomings of the these methods.Meanwhile,the applications and development trends of CNC photonic films in the fields of solar cells,information anti-counterfeiting,optical sensors and liquid crystal materials are analyzed.Finally,the challenges facing CNC photonic thin films are outlined to reveal potential application scenarios.
