Overview

Randomized trial quantifies mechanical effects of intrachain conformational locking in hydrogels, indicating its significance in material performance.

Key Points

  • This research aims to quantify the mechanical contribution of intrachain conformational locking in covalently cross-linked hydrogels.
  • Used a solvent-exchange strategy in poly(acrylic acid) hydrogels
  • Isolated local intrachain constraints by suppressing weak interactions
  • Introduced an Ω-chain model for network deformation analysis.
  • Identified intrachain conformational locking as a factor in mechanical response
  • Showed measurable changes in mechanical properties by modulating intrachain constraints
  • Demonstrated local folding affects load-bearing capacity under small deformation.
