Overview

Experimental analysis shows improved water resistance and rapid biodegradation in cassava-chitosan bioplastics, highlighting viable alternatives to petroleum-based thermoplastics.

Key Points

  • Adding chitosan to cassava starch produces bioplastic films with high compressive strength, conferring improved resistance against water molecules.
  • Water contact angle increases from 67.4° to 97.8° after chitosan addition, confirming greater hydrophobicity and enhanced tensile strength in the biopolymer.
  • Assessment using attenuated total reflectance fourier-transform infrared spectroscopy confirms chemical blending, supporting sustainable alternatives to single-use thermoplastics.
