摘要

Polymer coatings were doped with low quantity, below 1.5% by weight, of metal and non-metal nanoparticles. The electrical properties, i.e. antistatic properties, volume resistance and temperature characteristics of dissipation factor tanδ, were investigated. Antistatic properties were examined by charge decay measurements after corona charging, using JCI 155 apparatus. The results showed that the various additives can increase or decrease the time of charge decay. Incorporation of nanosilica to polymer much deteriorated the antistatic properties, due to barrier properties of nanosilica. On contrary the adding of nanosilver did not elongate the time of charge decay. The volume and surface resistivity at room temperature increases after adding a small amount of the conducting nanoadditives. It was proved that the tantanδ curves of coatings with nanosilica, as opposed to compounds with nanosilver, shift to higher temperatures. Therefore, application of nanosilica into polymer causes that the orientation polarization begin at higher temperature that results in the better thermal stability of modified coating. It was stated that nanosilver can improve antistatic properties without deterioration of dielectric properties of coating. On the other hand nanosilica additive results in the worse antistatic properties.
