Chitosan(CS) and cellulose acetate(CA) composite films were prepared using formic acid as a
cosolvent by casting, solvent evaporating and neutralization method. This study examines if the blending method,
which uses formic acid as a cosolvent is efficient in improving the mechanical properties of CS film, especially
wet strength and elongation. Formic acid is an effective cosolvent for the blend of CS and CA. Under wet
condition, tensile strength and elongation of the composite films were obviously higher than those of the films
made from pure CS. FTIR, DSC, and X-ray diffraction showed that the composite films exhibit a high level of
compatibility and that strong interaction between the CS and CA was caused by intermolecular hydrogen
bonding. The affinity series of composite film to transition metal ions are Cu(II) > Cd(II) > Cr(III). The adsorption
of Cu((II) ion was shown to be highly pH sensitive. |
