Abstract:A facile chemical vapor deposition (CVD) method is developed to modify graphene nanosheets with molecular-sized polydimethylsiloxane (PDMS-GNSs) in this work. Influences of the surface modification on microstructure and dispersibility of GNSs, as well as their performance as anticorrosion pigments, have been investigated. The experimental results show that the morphology of PDMS-GNSs is similar to that of GNSs, the thickness of PDMS-GNSs increases 0.23 nm as compared to GNSs, and PDMS-GNSs exhibit a significantly enhanced dispersibility in common paint solvents and ability to reinforce the anticorrosion performance of epoxy coating. This method has wide application prospects in anticorrosion field. (C) 2018 Elsevier B.V. All rights reserved.
