Abstract

Electric and optical properties of polymer films, which were prepared on the basis of polyimides and metallized by binary aggregates Ag with Ni and Co have been investigated. The metallized polyimide films with additional coating from Ni, Au and Rh have been studied too. It has been found that the temperature dependence of the specific surface resistance in the metallized films at the temperature from 25 up to 160°С was in the well agreement with linear law. The specific surface resistance at 20°С and temperature coefficient showed low values and was 0.16 – 2.24 W and 0.69´10-4 – 19.18´10-4 К-1 respectively. The film reflection coefficient in visible spectrum field at wavelength of 530 nm was 75% and essentially enlarged with wavelength increasing.
