Conductive property of carbon-nanotube dispersed nanocomposite coatings for steel

Abstract

Nanostructured modification of polymers has opened up new perspective for multi-functional materials. Carbon-nanotubes have the potential to increase the conductivity of their composite, with improved or retaining mechanical performance. This study focuses on the evaluation of the thermal and electrical conductivities of carbon-nanotube filled alkyd resins for steel coatings. Polymer/Carbon-nanotube nanocomposites have been pepared by mixing commercial multiwall carbon-nanotubes with alkyd resins and by curing. The thermal and electrical conductivities of carbon-nanotubes filled nanocomposite was found to be increased comparing with the original resin without any fillers or with the resin with carbon-black or carbon-nanofiber.
