Abstract:
Semi interpenetrating polymer network’s (IPN) hydrogel from bacterial cellulose (BC) has been successfully synthesized. This semi-IPN hydrogel was prepared from a suspension of BC in a solvent system of PEG1000/NaOH in the presence of acrylic acid (AA) as monomer, potassium persulfate (KPS) as initiator, and N,N’-methylenebisacrylamide (MBA) as crosslinker. The obtained semi-IPN hydrogel was characterized using FT-IR and SEM, also its physical property was characterized, i.e. swelling degree and crosslinked percentage. The swelling degree and crosslinked percentage showed the semi-IPN’s hydrogel with the addition of 600 mg BC has the maximum value, 1338 and 46%, respectively. The FT-IR analysis exhibited the crosslinked formation between AA and MBA with the presence of band at 1555 cm-1 that assigned as secondary aliphatic amine. The morphological analysis of semi-IPN’s hydrogel has a rough and dense surface.
