Mechanochemical Reinforcement of Graphene Sheets into Alkyd Resin Matrix for the Development of Electrically Conductive Paints

摘要

In this work, we are reporting the preparation of graphene-based conductive paints using mechanochemically prepared graphene nanosheets as a conductive pigment and alkyd resin as the binder with non-toxic additives. The surface morphology and intermolecular interactions between the graphene pigments and alkyd resin in the prepared graphene nanopaint are studied using field emission scanning electron microscope, X-ray photoelectron spectroscopy, and Raman spectroscopic analysis, respectively. The formation of percolation pathways owing to the interconnected graphene sheets in the paint matrix resulted in an excellent conductive behavior of the as-prepared graphene paint, thus ensuring its applications in conductive paint technology. Furthermore, Raman mapping analysis (including intensity maps and peak position maps) was used to understand the spatial distribution of graphene sheets in the alkyd resin matrix of the paint.
