Overview

This study demonstrates the effective formulation of bioplastic with favorable tensile strength and biodegradability, indicating potential for sustainable materials.

Key Points

  • The bioplastic exhibits a tensile strength of 52.53 N/mm2 and elongation of 22.64%, indicating strong mechanical properties.
  • Analysis showed an optimal starch-to-chitosan ratio of 40:60% with 20% sorbitol, resulting in significant biodegradability.
  • The solution casting method produced bioplastic with rapid biodegradability and favorable physical properties under specific heating conditions.
  • FTIR and TGA analyses revealed essential functional groups and multiple degradation stages, emphasizing the material's composition.
