Objective - To determine the fundamental laws between the behavior of electrical conductivity, optical absorption, photoluminescence, IR absorption, Raman scattering, morphology, crystal structure, thermophysical, dielectric and mechanical properties in individual systems, including various polymer matrices, my \additives, as well as polymer composites, including their radiation functionalization, quantum chemical modeling to establish mechanisms for enhancing tunneling conductivity and the occurrence of photosensitization of fillers. Research methods - structural, optical, electrical conductivity, dynamic method of ultrasonic waves, electronic irradiation, computer simulation. Percolation and photosensitization studies have been conducted properties and 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 the content of ligands. It was found that in the films of polymers of polyethylene glycol (PEG) and polypropylene glycol (PPG) with multi-walled carbon nanotubes (BVNT) percolation conductivity curves characterized by small values ​​of percolation thresholds φsPEG-BVNT = 0.0003, φs PPG-BVNT = 0.0002 vol. part., respectively. It was found that the presence of conjugation in the nanocomposites of PEG-BVNT and PPG-BVNT films leads to photosensitization of the Van Hov singularities of carbon nanotubes.  Product Description popup.authors Alyeksandrov Maksym A.
