CNC particles vary in size depending on their source:
- Pulp or Cotton-Derived CNC: Width ranges from 10 to 20 nanometers (nm), with lengths between 50 and 400 nm.
- Tunicate-Derived CNC: Width remains between 10 to 20 nm, but lengths extend from 500 nm up to 2 micrometers (μm), resulting in an aspect ratio of approximately 75.
These nanocrystals boast a crystallinity index exceeding 70%, indicating a high degree of structural order. In suspension form, CNCs resist hard agglomeration and can be redispersed in water after drying, especially with ultrasonic treatment. Notably, CNCs modified through organic acid hydrolysis (CNC-OA) can disperse in organic solvents. The solid content of CNC suspensions typically ranges from 0.5% to 10%.
Chemical modifications, including anionization, cationization, carboxymethylation, and polymer grafting, can be applied to CNCs to tailor their properties for specific applications. These versatile nanomaterials hold promise across various industries, from environmental remediation and engineering to pharmaceuticals and biodegradable packaging. Their potential to replace petrochemical-based products offers a sustainable and cost-effective alternative in the realm of high-performance nanomaterials.
