- ... The major limitation in the development of hybrids based on graphene oxide (GO) and porphyrins is their dispersibility and stability in aqueous systems due to the hydrophobic character induced by porphyrins. Most of the previous approaches reported the direct functionalization of GO with polyethylene glycol (PEG) chains followed by the self-assembly of porphyrins by π-π interactions. Here, new hyb ...

- ... Friction and wear of motion components operating under harsh lubrication conditions are key aspects that must be considered in vast numbers of applications. In the present work, graphene oxide (GO) functionalized in-situ with ionic liquid (IL) were uniformly dispersed into epoxy (EP) via a two-phase extraction route. In comparison to as-exfoliated GO, GO functionalized with IL (GO-IL) showed signi ...
