Effect of sisal fiber on retrogradation and structural characteristics of thermoplastic cassava starch

Thermoplastic cassava starch (TPS)/sisal fiber (SF) composites were prepared by the melting method. The effect of SF on retrogradation kinetics, morphology and size spherulites, molecular interactions, short-range structure, crystal type TPS was investigated. results indicate that degree rate increase with addition SF, spherulites become clearer denser. neat sample forms an A-type through double helix structure a V-type single structure. After TPS/SF composite decreases increases. With further content, mainly presents crystal. has higher crystallinity, but smaller interplanar spacing. storage modulus, loss glass transition temperature (T g ) get enhanced SF.
