Descrizione generale
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.
Applicazioni
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.

Millimeter to centimeter-sized injectable neural scaffolds based on macroporous cryogels are presented. The polymer-scaffolds are made from alginate and carboxymethyl-cellulose by a novel simple one-pot cryosynthesis. They allow surgical sterility by means of autoclaving, and present native laminin as an
