| Abstract | ||
| In this study Cross-linked PVA/Pullulan film was prepared. Cross-linking reaction done by addition of gluteraldehyde at different reaction time (10,30and 60) min. Chemical interaction, mechanical, thermal properties, water solubility and film morphology was studied for cross-linked PVA/Pullulan, PVA and Pullulan only. Thus FTIR investigated formation of hydrogen bonding between pullulan and PVA with (GA). Tensile strength, tensile modulus and elongation (%) at break for PVA/Pullulan film was improved with addition of (GA) as the reaction time proceed equivalent with increasing PVA content | ||
