Synthesis and Characterization of starch-maleate-chitosan nanocomposite film
Starch-maleate-chitosan (SMC) nanocomposite films were prepared from a mixture of starch-maleate and chitosan nanoparticles. The effect of components ratio on the physical and antibacterial properties of prepared films were investigated by FTIR, SEM, water absorbency and zone inhibition test. FTI...

| Summary: | Starch-maleate-chitosan (SMC) nanocomposite films were prepared from a mixture of
starch-maleate and chitosan nanoparticles. The effect of components ratio on the physical
and antibacterial properties of prepared films were investigated by FTIR, SEM, water
absorbency and zone inhibition test. FTIR revealed the bonding between starch-maleate
and chitosan nanoparticles. The water absorbency of SMC nanocomposite films were
showed increased as chitosan nanoparticles amount increased. This was due to the chitosan
itself was hydrophilic and with poor-water barrier characteristic. The nanocomposite films
had shown inhibition effect against E. coli when investigated qualitatively by zone
inhibition method. However, increase in chitosan nanoparticles volume did not
significantly increased the antibacterial effect. |
