Rezumat: This work is devoted to the study of polymer nanocomposites with reduced flammability based on polypropylene (PP), with carbon nanotubes (CNTs) being used as additive. This research was done by density functional theory (DFT) using a software package PC GAMESS. A quantum-chemical model that characterizes the interaction of the fragments of the polymer chains (oligomers) with the filler particles surface has been proposed. The effect on the molecular structure of PP by nano-additives, the surface of which is modified by different functional groups (COOH, OH-, F-) has been studied. Results of the study allowed formulating possible mechanisms of the influence of nano-additives on the combustion parameters of nanocomposites based on PP at the molecular level. The recommendations for choice of functionalization method of CNTs in the development of polymer nanocomposites with reduced flammability has been formulated based on a comparison of different modification methods.
