  • Can graphene-based polymer hydrogels be prepared by frontal polymerization?
  • Despite enormous reports on graphene/polymer composites, only a few investigations are devoted to graphene-based polymer hydrogels. Among them, graphene-containing thermoresponsive nanocomposite hydrogels of poly (N-isopropylacrylamide) (PNIPAM) have been prepared by frontal polymerization .
  • Are graphene nanosheets arranged in a fibrous network of polypyrrole?
  • In this study, graphene nanosheets are arranged in a fibrous network of polypyrrole, acting as current collectors in the multilayer bulk electrode configuration. The graphene nanosheets are distributed and form a network where they share edges and interconnect with each other to create an electrically conductive pathway within the bulk electrode.
  • Does graphene aerogel increase electrode capacitance retention?
  • They reported a preparation of PPy/GO@graphene aerogel using pulse electrochemical synthesis . The presence of graphene aerogel in the composite (PPy/GO@graphene aerogel) increases the electrode capacitance retention up to 30 % higher than the PPy/GO electrode measured at the current densities ranging from 1 to 15 A g −1.
