Overview

Randomized trial demonstrates enhanced mechanical properties in bio-based hydrogels, indicating potential for tissue engineering applications.

Key Points

  • This study aims to develop tough, bio-based hydrogels with improved mechanical properties through the alignment/drying and salting out strategy.
  • Utilized an effective structure-molecule engineering strategy called Alignment/Drying and Salting Out (ADSO).
  • Constructed high-amylose/polyvinyl alcohol (HSPI-ADSO) hydrogel with a hierarchical anisotropic structure.
  • Performed microscopic structure characterizations and finite element simulations to analyze the hydrogel properties.
  • HSPI-ADSO hydrogel achieved tensile strength of 4.18–17.40 MPa and elongation at break of 258%–1086%.
  • Young's modulus ranged from 3.33 to 37.43 MPa, with toughness measured at 7.60–71.63 MJ·m−3.
  • ADSO strategy effectively adjusted mechanical properties of various natural polymer-based composites.
