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 to stabilize palladized iron nanoparticles, which can further be utilized in the dichlorination of contaminated subsurfaces. It may also be used as a polymeric matrix to form a composite with a crystalline nanofibril for the development of sustainable bio-based polymers. CMC can also bind with a hard carbon electrode for the fabrication of sodium ion-batteries.
