Copper nanoparticles decorated graphene nanoplatelets and composites with PEDOT:PSS

A facile and reliable synthesis route to Cu-graphene nanoplatelets (GNP) hybrid films has been developed. Cu nanoparticles of 13.7 +/- 3.4 nm mean size were attached to few-layer graphene sheets. The obtained composite has good film forming properties and resistance of 380 Omega as compared to pure GNP, forming unstable and weakly conductive films. Introducing the GNP-CuNP nanofiller into the conducting polymer PEDOT:PSS leads to a more pronounced improvement of the conductivity of the latter compared to the case of using pure GNP. A simple way to produce a stable and highly conducting composite for manifold printable electronics applications is demonstrated. (C) 2016 Elsevier B.V. All rights reserved.
