Polymer thin films from electrical discharges of hydrocarbons show great technological interest due to their auspicious applications, notably in the mechanical, microelectronic industry, and preparation of biomaterials. In this work, it was studied the correlation of the plasma phase with the polymer phase, formed in benzene discharges excited by continuous voltage of 1,0 kV under pressures which varied from 0,2 to 1,0 mbar. In this pressure range, the electronic temperature varied from 1,5 to 4,3 eV. The polymer phase showed continuous fine film morphology or fine film form with powder, containing OH, CH3 e CH2 radicals, and the polymer growth rate was between 40 and 160 Å/min. The thermal diffusivity of these materials was measured between 1,0 x 10-3 cm2/s and 2,7 x 10-3 cm2/s.
