Fabrication and Characterization of Biomass-derived Superabsorbent Bio-gel

Superabsorbent polymers (SAPs) are functional macromolecules with high water absorption and retention capacities. Nowadays, carboxymethyl cellulose (CMC) nanofibrils (CMCNFs) widely utilized as absorbent materials to replace petroleum-based SAPs, which lead environmental pollution. However, their water- holding characteristics inferior compared those of SAPs. In this study, we explore the polymerization CMC CMCNF bio-gels acrylic acid using two distinct production routes compare saline capacity these biomass-based absorbents. It was suggested that concurrent treatment solvent exchange addition powder during homogenization improved final bio-gel. Furthermore, 30% found increase initial by up 52%.
