Study on Nanocellulose / Starch Composites

Abstract:

Nanocellulose and thermoplastic starch polymer (TSP) composite was prepared by solution casting method for the sports industry. As a biological material, this material had special properties of nanomaterials and the rigidity of cellulose, dimensional stability and biodegradable. Such material might be one of the answers to the disposal problem of waste sports equipments. As a reinforcing material, nanocellulose was added to TSP matrix and composites were made with appropriate solvent systems by solution casting methods. Water absorption, degradation and film mechanical performance were evaluated and compared with the pure thermoplastic starch. The tensile strength and modulus of the nanocomposite films reveled significantly enhanced. Compared to the pure thermoplastic starch, the degradation and water absorption increased significantly. By solution casting, nanocellulose and starch composites were successfully prepared, which had excellent mechanical properties and good performance at biological degradation.
