The results of antistatic and electrical properties investigations of nanofilled coatings have been presented. Antistatic performance of materials is essential not only due to safety and preventing of dust and dirt attraction but also effects on an electrical field distribution in the high voltage insulating systems. The polymer coating added with silver and silica nanoparticles were examined by charge decay measurements after corona charging. The charge decay times have varied appreciably between the nanofilled coatings while the volume and surface resistivity of the all tested coatings did not demonstrate meaningful differences. The polyester coating dissipated fairly better than polyesterimide because of its structure and permittivity. It was found that the ability of surface to drain charge away is the better for coatings with of silver nanoparticles whereas the coatings modified with nanosilica shows the poor antistatic properties; the times of charge decay were four order longer then that of unmodified coatings. Barrier properties of nanosilica may be adverse for charge decay.
