The novel hyperdispersant for CNT in waterborne paint and its metal corrosion protection behavior
Source abstract
Abstract
The carbon nanotubes (CNT) have great potential as a metal intelligent anti-corrosion additive due to its excellent conductivity, mechanical property and large specific area. However, their uniform dispersion in the matrix without chemical modification still remains a great challenge, not to mention the corresponding potential mechanism. Herein, a novel hyperdispersant, polymethyl naphthol sulfonate (PMNS), is developed to improve the dispersivity of CNT in a polymer matrix according to the high adsorption energy (− 0.919 eV) of PMNS on the CNT surface calculated by the density functional theory (DFT). This resulting aqueous CNT/acrylate grafted epoxy nanocoating has a conductivity percolation value as low as 0.175 wt%. The CNT(0.25 wt%) nanocoating presents the best both in seawater immersion resistance and in the salt spray resistance improved by 75% in comparison with unfilled coating. The metal corrosion prevention mechanism is revealed to be good dispersibility in polymer matrix and the effective cathode suppression effect caused by the formation of CNT conductive networks revealed by Tafel polarization curves and electrochemical impedance tests.
