The surface morphology of the polymer films based onpolyepoxypropylcarbazole and 3,6-di-Br-polyepoxypropylcarbazole with V2O5 was investigated by Atom Force Microscopy (AFM). The surface of composite has been found to be a chaotically intertwining of V2O5 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 V2O5 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 V2O4 molecule and 3M PEPC oligomers with V2O5 molecule have been observed in mass spectrum of PEPC+V2O5 composite at the emitter temperature from 120degreesC up to 430degreesC. 2M, 3M and even 5M PEPC olygomers were observed in mass spectrum of 3,6-di-Br-PEPC+V2O5 composite at the emitter temperature from 20degreesC up to 600degreesC and 2M 3,6-di-Br-PEPC at the emitter temperature above 200degreesC. In this mass spectrum the ions which can be identified as PEPC oligomer complexes with V2O3 , V2O4 and V2O5 molecules and as 3,6-di-Br-PEPC monomer complexes with V2O3 , V2O4 molecules were also observed. Some observed ions can be also identified as Br-PEPC (with one atom of Bromine) monomer complexes with V2O4 and V2O5 molecules.
