Popis: The surface morphology of the polymer films based onpolyepoxypropylcarbazole and 3,6-di-Br-polyepoxypropylcarbazole with V 2 O 5 was investigated by Atom Force Microscopy (AFM). The surface of composite has been found to be a chaotically intertwining of V 2 O 5 fibres intermittent with inclusions of a corresponding polymer. Polymer inclusions are single ellipsoidal grains for PEPC composite and an aggregate of small grains for 3,6-di-Br-PEPC sample. Both V 2 O 5 fibres and polymer inclusions have smaller size in 3,6-di-Br-PEPC. The mass spectra of compounds under investigation have been obtained. Both PEPC oligomer ions and those identified as complexes of M PEPC oligomers with V 2 O 4 molecule and 3M PEPC oligomers with V 2 O 5 molecule have been observed in mass spectrum of PEPC+V 2 O 5 composite at the emitter temperature from 120°C up to 430°C. 2M, 3M and even 5M PEPC olygomers were observed in mass spectrum of 3,6-di-Br-PEPC+V 2 O 5 composite at the emitter temperature from 20°C up to 600°C and 2M 3,...
