This study presents a straightforward route to fabricate robust poly(vinyl alcohol) (PVA)/polyethyleneimine-functionalized graphene (PVA/rGO/PEI) composite films by combining of surface modification, reduction and composite preparation. Branched polyethylenimine (PEI), as an effective reducing agent and surface modifier of graphene oxide (GO), has been presented to yield PEI-functionalized graphene...
Poly(vinyl alcohol) (PVA)/reduced graphite oxide (rGO) nanocomposites were synthesized by solvothermal reduction of graphite oxide (GO) in the presence of PVA. The solvent, the mixed dimethyl sulfoxide (DMSO)-dimethylformamide (DMF), could act not only as a reducing agent but also as a good stabilizer, which achieved effectively reduction of GO in the PVA matrix and avoided the agglomeration of rGO...
