Anti-corrosion efficiency of pigment-free epoxy novolac/lowered graphene oxide composite coatings: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0

Summary

Purposeful or good coatings (natural, inorganic, or hybrid) are fashioned by supplies that may be tailored for a lot of functions the place they need to be capable of carry out a well-defined set of capabilities, equivalent to bettering chemical, mechanical, electrical, and magnetic properties of the substrate. This undertaking studied the anticorrosive effectivity of nanoaditivated pigment-free epoxy coating by the addition of rGOL within the contents of 0.1 and 0.5 wt%. XRD, AFM, FTIR, and Raman spectroscopies have been employed to acquire related info on the molecular construction and interplay between epoxy resin and rGOL. Thermogravimetry outcomes didn’t point out a major change in polymer matrix T_g. This could possibly be associated to an incomplete curing technique of the resin and/or the presence of defects within the rGOL pattern. All of the corrosion assessments outcomes indicated that the rGOL addition promotes enhancements to the epoxy corrosion resistance reached by a barrier mechanism.
