Surface modifications of graphene-based polymer nanocomposites by different synthesis techniques [PDF]

, 2012
With the appropriate surface treatments, graphene sheets can be separated from graphite material and the layer-to-layer distance can be extended. In the present work, graphene nanosheets (GNS) were separated from graphite by an improved, safer and mild ...

Electrosynthesis of polyacrylic/polypyrrole composites: Formation of polypyrrole wires [PDF]

Synthetic Metals, 1999
Abstract A new preparation method is reported for the synthesis of conducting polypyrrole nanowires. This two-step all-electrochemical method consists in the cathodic grafting of a thin polyacrylate film on a carbon electrode, which is then used as an anode for the electropolymerization of pyrrole.
