ABSTRACT
The objective of this study is to investigate the synthesis of films of chitosan– starch–glutaric acid and its characterization. The films were synthesized using chitosan, starch, and crosslinked with and glutaric acid. The variation of concentration of chitosan-starch was 0.1/0.9 from 0.9/0.1. These films were characterized by percentage of swelling, FTIR. The swelling study was conducted in pH 2.2 and 7.4. The percentage of swelling was increased with increasing the concentration of chitosan and also increased with release time increasing. The percentage of swelling is more in basic medium at pH 7.4. The cryastalinity of films were increased by adding starch and also increased cryastalinity of films with crosslinking glutaric acid. FTIR study also supported that the films were crosslinked with different crosslinking agents.
