dielectric capacitivity increase of cyanic ester of polyvinyl alcohol and its composite with barium titanate by electron beam treatment
The modification of the cyanic ester of the polyvinyl alcohol (CEPA) by means of treatment with accelerated electrons with energy of the 700 keV at dose of the 150 kGr has been shown to result in the increase in its dielectric capacitivity to 2.5 times and in the increase in optical transparence in visible part of spectrum. The dielectric capacitivity increase has been observed at the same treatment of the CEPA composites with the barium titanate which were used in composition of electroluminescent light sources.
