Effect of nanoclay on electrical and mechanical properties of polyurethane conductive coatings filled with nickel-coated carbon fibers

There is a considerable amount of researches focused on the properties of nanocomposite containing nanoclays, yet there were only few studies about nanoclay conductive coatings. The influence of montmorillonite nanoclay on the electrical and mechanical properties of polyurethane conductive coatings filled with nickel-coated carbon fibers was investigated in this study. Moreover, the role of nanoclay with regard to the resistivity of coatings with different conductive fillers or different resins, the effects of resin to hardener ratio and mixing time on the resistivity and hardness of coatings were also evaluated.
