Stepwise salting-out and freeze-thaw strategy enables robust conductive polyvinyl alcohol hydrogels via interfacial synergy for multifunctional wearables.
To address the intrinsic trade-off between mechanical robustness and ionic conductivity in polyvinyl alcohol (PVA) hydrogels arising from structural heterogeneity, this work presents a stepwise salting-out and freeze-thaw cycling strategy to fabricate high-performance composite hydrogels with synergistic interfacial in...
