General description

Sodium carboxymethyl cellulose (CMC) is a water dispersible sodium salt of carboxy-methyl ether of cellulose that forms a clear colloidal solution. It is a hygroscopic material that has the ability to absorb more than 50% of water at high humidity. It is also a natural polymeric derivative that can be used in detergents, food and textile industries.

Application

CMC can be used as a binder in the preparation of graphene nano-platelet based inks for the fabrication of dye sensitized solar cells (DSSCs). It can also be used as a viscosity enhancer in the development of tyrosinase based inks for the formation of electrodes for biosensor applications. CMC is used as a support material for a variety of cathodes and anodes for microbial fuel cells.
