Synthesis and Characterization of Chitosan Based Films Prepared from Narmada Riverside Crab Shells

Abstract

The present article describes the preparation and characterization of chitosan based films. The raw material was collected from Narmada riverside crab shells. The SEM images were taken for crab shell powder obtained from Narmada river side crab shells to observe the morphology. The chitin, chitosan and chitosan based films developed from the crab shell were also examined for morphology. The SEM photographs of crab shell powder, prepared chitin and chitosan exhibited rough and thick surface morphology under electron microscopic examination. The pure chitosan film demonstrated uniform and homogenous surface confirming the formation of an ordered film structure. Unlike the pure chitosan film, the surface of plasticized films became coarse and exhibited small cluster of particles attributed to glycerol presence. The XRD analysis of prepared chitosan films was performed. The pure chitosan film found to be amorphous in nature. Wide hump observed at 2θ=11.23 and 23.92. As a function of doping with different glycerol percentage it become crystallized.
