개요

Cellulose Nanocrystals (CNC)‌ are derived from plant cellulose, the most abundant natural polymer on Earth. Through chemical or mechanical processing, cellulose can be broken down into nanoscale cellulose crystals. These crystalline whiskers typically exhibit a highly ordered structure, with lengths ranging from tens to hundreds of nanometers and diameters from a few to tens of nanometers.

1. Storage and Handling

‌Storage Conditions‌: CNC is commonly supplied as a powder or suspension. The powder should be stored in a ‌dry environment‌ to prevent moisture absorption, while suspensions should be kept at ‌low temperatures (e.g., 4°C)‌ to inhibit microbial growth.

‌Handling‌: When handling the powder, wear a ‌mask and gloves‌ to avoid inhalation and skin contact. Suspensions should be processed in a ‌clean environment‌ to prevent contamination.

2. Dispersion and Dispersant Selection

CNC tends to aggregate, so appropriate dispersants (e.g., surfactants) or ‌high-shear mixing‌ are required for effective dispersion.

‌Preparation Methods‌: Uniform CNC suspensions can be prepared using ‌ultrasonication, mechanical stirring, or high-pressure homogenization‌. Process parameters such as duration and power should be optimized based on the intended application.

3. Application Areas

‌Reinforcement in Composites‌: CNC is widely used to enhance polymer-based composites. Uniform dispersion of CNC in the polymer matrix can significantly improve mechanical strength.

‌Coatings and Films‌: CNC enables the fabrication of transparent films or coatings. By adjusting CNC concentration and dispersion state, optical and mechanical properties can be precisely controlled.

‌Water Treatment‌: CNC can serve as an adsorbent in water purification. After chemical modification or functionalization, CNC efficiently removes ‌heavy metal ions or organic pollutants‌.

‌Other Applications‌: Stabilizer for ‌soap-free emulsions‌ in cosmetics, pharmaceuticals, and food; biodegradable reinforcing agent or filler in plastics.
