The filler form should advantageously influence the barrier properties of the thermoplastic polymers, filled with such nanofillers.

Varnishes modified with nanoparticles for use in electrical insulation

“…Nanotechnology enable to develop the new advanced dielectrics which show not only better mechanical, thermal and barrier properties [1][2][3][4] but also display the better dielectric properties because the large development of surface activity in nanofilled polymers results in reduced charge mobility, what in turn should bring the significant change in electrical properties [5][6][7]. If the size of the incorporated particles approaches that of the polymer chain length, the particles stop to behave like foreign inclusions and space charge densities are very small.…”
