The intramolecular structure and conductivity characteristics of the PE–MWCNT and PE–MWCNT–DBSQ nanocomposites are studied. As shown for the PE–MWCNT and PE–MWCNT–DBSQ nanocomposites, there is a change in the intramolecular structure and the reorganization of the polyene sequences that manifests itself in the shift of vibrational modes ?(C–C), ?(C???O), ?(CH2) in the spectrum of Raman scattering and the emergence of new emission centres in the photoluminescence spectra. As revealed in the PE–MWCNT nanocomposite, the electrical conductivity is improved by ????10 Cm/cm, while in the PE–MWCNT–DBSQ nanocomposite, there is a slight decrease by ????1 Cm/cm that is related to the aggregation of MWCNT and DBSQ.

Keywords: multiwalled carbon nanotubes (MWCNT), DBSQ dyer, intramolecular structure, electrical conductivity
