Implication

Experimental study demonstrates high-strength, super-extensible nanocomposite hydrogels derived from graphene peroxide, suggesting a robust method to boost graphene-polymer interfacial bonding.

Key Points

  • To develop an effective method for synthesizing graphene peroxide via radiation-induced peroxidation and evaluate its utility in creating ultra-stretchable, resilient polymer nanocomposite hydrogels.
  • Synthesized graphene peroxide (GPO) through the radiation-induced peroxidation of graphene oxide (GO) sheets.
  • Confirmed the formation of peroxide groups on GO sheets via iodometric titrations and standard material characterizations.
  • Employed GPO as a multifunctional initiator and cross-linker to drive in situ grafting polymerization into composite hydrogels.
  • GPO-derived composite hydrogels achieved tensile strengths ranging from 0.2 to 1.2 MPa.
  • Synthesized hydrogels exhibited extreme elongations between 2000% and 5300% along with high mechanical resilience.
