The influence of diamond blend on the
resistance of polyimide films to atomic oxygen
Abstract
Film samples based on polypyromellitimide
and polyamidimide and their modifications with carbon filler (diamond blend)
have been exposed to atomic oxygen flow with an average energy of 20 eV.
According to the obtained data the calculation of the mass erosion coefficients
of the original and modified polyimide and a comparative analysis of the
resistance of samples were made. The changes in morphology of polymer surfaces
after exposure were studied with scanning electron microscopy. It was shown
that increasing the filler contentin the polymer matrix has slightly improved polymer resistance to
the atomic oxygen attack.
Key words:atomic oxygen, polypyromellitimide,
polyamidimide.
