The influence of diamond blend on the resistance of polyimide films to atomic oxygen

Resumo

Poly-pyromellitimide and polyamideimide film samples and their modifications obtained with a carbon filler (diamond blend) were irradiated with atomic oxygen flow at an average particle energy of 20 eV. Weight erosion coefficients were calculated for the initial and modified polyimides and a comparative analysis of the resistance of the film samples was carried out. The morphology of the film surface was studied after irradiation with atomic oxygen via scanning electron microscopy. An increase in the percentage of filler in the polymer matrix caused a slight increase in the resistance of the film samples to the effect of atomic oxygen.
