Achieving cellulose nanocrystal (CNC) powder with excellent dispersibility and scalability.
*Please note that even if you contact us via "Download Catalog" below, we will not be able to confirm the content. For inquiries, please use "Contact Us via Web."* <Background and Issues> Cellulose nanofibers (CNF) and cellulose nanocrystals (CNC) are attracting attention as next-generation resin fillers due to their lightweight and high-strength properties. However, conventional methods often lead to aggregation and crystallization during the drying process, making re-dispersion in water or resin difficult. As a result, CNC is primarily distributed as an aqueous dispersion, facing challenges in transportation costs and storage stability. <Technical Overview> This technology provides a method to obtain powdered CNC through a simple process of grinding microcrystalline cellulose in a low-dielectric organic solvent and then drying it. - Grinding → Drying → Powdering - No special surface treatment required - Efficient grinding even under high concentration conditions <Verification Data> - In comparisons based on solvent treatment, good powders were obtained with toluene and cyclohexane treatments, confirming excellent re-dispersibility. - SEM observations confirmed that the fine powder suppresses crystallization and aggregation.
