Abstract

The chitosan-roselle films were fabricated by casting method. The roselle ratio and cure temperature of films were varied to study the thermal properties of the chitosan-roselle films. Thermal properties of chitosan-roselle films showed higher heat resistance when blend roselle ratio and cure temperature were increased. The temperature at maximum degradation rate of chitosan-roselle films was determined by DTG. The chitosan-roselle films were degrade faster when the roselle ratio increased at ambient temperature. The cure temperature was varied to 50 0C, 60 0C and 70 0C, the most optimum cure temperature was 60 0C which showed the lowest weight loss and exhibited the highest heat resistance compared to the other cure temperature. SEM results showed the surface structure of different ratio of chitosan-roselle films which were cure at 50 0C, 60 0C and 70 0C. The surface structure become smoother when the ratio of chitosan-roselle was increased. FTIR result showed that the intensity percentage of functional group exist in pure chitosan films were improved by adding roselle to become chitosan-roselle films. The results showed the most optimum cure temperature was 60 0C which showed high intensity percentage compared to the other cure temperature.
