Product Appearance
SM-CNCs typically present as a fine, white powder, easily dispersible in water across a broad pH range (1–14).
Product Characterization
The incorporation of sulfonic acid groups on the cellulose nanocrystals' surfaces enhances their hydrophilicity and stability in aqueous solutions. This modification facilitates the formation of stable emulsions and gels, making SM-CNCs suitable for various industrial applications.
Instructions for Use
To effectively utilize SM-CNCs:
Pre-Dispersion: Pre-disperse the powder into a high-concentration colloid using high-speed mixing.
Integration: Combine the colloid with the target product.
Dispersion: Stir and disperse the mixture using conventional equipment to achieve uniform distribution.
Applications
SM-CNCs offer versatile functionalities across multiple industries:
Water-Based Systems: Serve as soap-free emulsion stabilizers, thickeners, thixotropic agents, reinforcing agents, and anti-cracking agents.
Biomedical Field: Enhance properties of biomaterials, such as hydrogels and scaffolds, improving cellular responses and tissue engineering outcomes. MDPI
