Product Description: Sulfonated Cellulose Nanocrystals (S-CNC) are prepared by introducing sulfonic acid groups (-SO3H) onto the surface of Cellulose Nanocrystals (CNC). Sulfonation modification enhances the hydrophilicity, charge density, and stability of cellulose nanocrystals in aqueous media, making them widely applicable in catalysis, adsorption, thickening agents, biomedical fields, and other areas.

Aqueous System Applications: Soap-free emulsion stabilizer, thickener, thixotropic agent, reinforcing agent, anti-cracking agent;
