Research Progress in the Preparation and Application of Carboxymethyl Cellulose Conductive Hydrogels
Carboxymethyl cellulose is an important cellulose derivative that has drawn much attention due to its accessibility,affordability,and environmental friendliness.This paper briefly introduced the physical and chemical preparation methods of carboxymethyl cellulose con-ductive hydrogels,described their mechanical properties,electrical conductivity,strain sensitivity,self-adhesion,self-healing,biocompati-bility,anti-freezing and water retention properties,elaborated their application in the field of sensors,supercapacitors,and batteries,sum-marizes the challenges encountered by them,and predicted their development direction in the future,thus provided a certain basis for the high-value utilization of carboxymethyl cellulose.
