Graphene@poly(m-phenylenediamine) hydrogel fabricated by a facile post-synthesis assembly strategy†
Abstract
The mixing of graphene oxide and protonated poly(m-phenylenediamine) (PmPD) nanoparticles generates floccus that can be readily transformed into graphene@PmPD hybrid hydrogel through redox reaction. This macroscopic material can be directly applied as a monolith column adsorbent for water purification.
