The film properties that obtained in the atmospheric pressure plasma from aniline

Abstract

The polyaniline (PANI) films filled by carbon particles can demonstrate the conductivity increasing. The carbon particles uniform distribution in the PANI films can be received by their contemporaneously formation in the atmospheric pressure plasma. The films properties produced from aniline contemporaneously with carbon particles in the atmospheric pressure plasma are considered in that paper. The energy density threshold (~ 30 mJ/m) of gas discharge starting from which it is possible to obtain a continuous film filled with agglomerates of carbon particles was defined. It was showing that the such films has the amorphous morphology. It was defined that the carbon particles agglomerates in the PANI films. The carbon particles agglomerates concentration in the PANI films is about ~(4 – 7)·104 1/cm2 and slowly depends on the energy density. So the conductivity of that films cant be increasing by this particles. It was shown that the films moisture saturation is the main reason of them conductivity increasing. It was shown that the films creep are decreases and the hardness increases when the gas discharge energy density increases. Its because the crosslinks number is growth in the samples. The molecular weight of PANI films is low, so the Martens hardness value has low-level.
