PREPARATION AND CHARACTERIZATION OF PVA CROSSLINKED FILM WITH CINNAMALDEHYDE

Abstract

This thesis report is based on the research in the field of crosslinking of polyvinylalcohol with cinnamaldehyde and their application in food grade packaging polymer. It was found that crosslinking of PVA with CIN has more benefit then uncrosslinked film formation. Crosslinked film leads the enhancement of properties such as water barrier , antimicrobial , optical , and mechanical properties raise in dispersible property, gain thermal and chemical stability. In the present experiment preparation and characterisation of pva crosslinked with cinnamaldehyde film using HCl studied. Prepared PVA crosslinked , uncrosslinked, pure PVA film were characterised by SEM, FTIR, Color test, Water absorbance ,WVTR. Further properties are investigated by polymer matrix using FTIR, and DSC-TGA.
