The purpose of the work is to determine the structural rearrangement in polymers due to their modification by π-conjugated fillers and radiation functionalization and to establish the mechanisms of charge carrier transport in these composites. Research methods - optical, electrical conductivity, electron irradiation, computer simulation. The study of percolation and photosensitization properties in the films of nanocomposites of polyethylene glycol (PEG) and polypropylene glycol (PPG) with multiwall carbon nanotubes (BVNT) and dyes and spectrophotometric studies of the concentration dependences of the optical properties of drugs on drugs. It was found that in the films of polymers of polyethylene glycol (PEG) and polypropylene glycol (PPG) with multiwall carbon nanotubes (BVNT), the percolation conductivity curves are characterized by small values ​​of percolation thresholds φсПЕГ-БВНТ = 0.0003, ,000БНТ = 0.0003-φС П. part., respectively. The binding constants for solutions of doxorubicin and albumin molecules in water at different temperatures were obtained, and changes in thermodynamic potentials were calculated, which indicate that the main mechanisms of interaction of these molecules in complexes are the occurrence of hydrophobic and electrostatic forces.  Product Description popup.authors Aleksandrov Maksym A.
