CELLULOSE NAN0CRYSTALS Effect of storage conditions on cellulose nanocrystal stability

摘要

Cellulose nanocrystals (CNCs) have evolved from a laboratory curiosity to an industrial material manufactured at a scale of up to one ton/day. Such large quantities of CNCs will inevitably be stored for different lengths of time before shipping and use. The chemical and physical stability of CNCs during long-term storage under various conditions was monitored. As-produced acidic H-CNCs and neutral salt form Na- CNCs were stored at ambient temperature and at 4°C as never-dried suspensions, and as a freeze-dried solid in the case of Na-CNCs.
