PREPARATION AND CORROSION RESISTACE OF EPOXY RESIN COATING WITH DOPAMINE MODIFIED BASALT FIBER

Abstract

Herein, the anti-corrosion properties of basalt fiber materials modified by bio-stimulation, which grows poly-dopamine in situ on the fiber surface by a chemical modification method. This approach not only triggers cross-linking reaction between the modifier and the resin during the curing process of resin, to form a body type network structure that is closely connected and runs through the whole curing system, but also enhances the interaction between modifier and epoxy resin. The electrochemical test revealed that the corrosion resistance of the composite coating is greatly improved by 21% compared to the pure epoxy coating.
