Overview

Randomized trial shows improved strength and toughness in cellulose bioplastic, indicating a potential for sustainable materials.

Key Points

  • The research aims to enhance strength and toughness in cellulose-based materials using a double-network structure.
  • Developed an all-cellulose bioplastic with a hierarchical hydrogen-bonding structure.
  • Delignified wood fibers into cellulose microfibers to create an interpenetrating network with regenerated cellulose nanofibers.
  • Conducted mechanical testing to evaluate tensile and compression strengths.
  • The AC-bioplastic achieved a tensile strength of 95.8 MPa and toughness of 84.8 MJ m −3.
  • Under a high strain rate of 4000 s −1, the bioplastic exhibited a compression strength of 200 MPa.
  • The material's performance surpasses typical cellulose-based materials and approaches polymeric elastomers.
