Preparation and Application Progress of Cellulose Formate
Cellulose esters represent a significant class of cellulose derivatives,which are extensively utilized in a multitude of industrial sectors,including textiles,food,packaging,electronics,medicine,chemicals,and military.Formic acid can esterify with the hydroxyl group on the surface of cellulose,thereby introducing ester groups on the surface of cellulose to form cellulose formate.In this paper,the preparation process of cellulose formate and its application in polymer filling,Pickering lotion,functional film,filament and other fields are reviewed,in order to provide reference for the large-scale preparation and application of cellulose formate in the future.The preparation of cellulose formate will develop towards a green and low energy consumption direction;Its application will be more diversified,especially in the development of high-quality and sustainable materials,as well as the further derivatization of functional materials,which has broad research prospects.
