Session: General Poster:

SAP(Superabsorbent polymer) is a functional material that can absorb and hold dozens of times more aqueous solution than its own weight. However, SAP made from petroleum-based polymers causes serious environmental pollutions due to its non-biodegradability, which is a driving force for developing a biomass-driven SAP. Cellulose is a rich natural resource and can produce absorbent materials with a structure that holds moisture by adding a cross-linking agent to the reforming cellulose in which cellulose hydroxyl are replaced carboxyl. This study aimed to fabricate superabsorbent bio-gels with acrylic acid and cross-linking agents to CMC(Carboxymethylcellulose) and CMCNF(Carboxylated cellulose nanofibrils) and then the saline absorption characteristics will be discussed.
