Preparation and Performance of Corona-proof Conductive Composite Coatings

Because of its merits, acrylic resin was chosen to improve the mechanical, conductive and hydrophobic properties. Carbon fiber powders (CF), carbon nanotubes (MWCNT), and nano-TiO₂ were incorporated into the acrylic resin to prepare the corona-proof conductive composite coatings. The incorporation of CF and MWCNT may improve the conductivity and mechanical strength of the coatings. However, the addition of nano-TiO₂ may increase the hydrophobicity of the coatings. Thus, the effects of different additives on the mechanical properties, conductivity, hydrophobicity and heat resistance of the conductive film were studied. The experimental results show that the incorporation of carbon fiber powders and multi walled carbon nanotubes can significantly improve both the conductivity and mechanical properties of the conductive coatings, and the addition of nano titanium dioxide can improve the hydrophobicity of the conductive film.
