Influence of the chemical structure and components concentration of the polymer/nanoparticles blends on the flow temperature

Abstract

Calculation scheme is suggested for estimating the flow temperature T_f of the system containing the polymer and nanoparticles. The chemical structure of the polymers and nanoparticles, the intermolecular interaction between the polymer and nanoparticles at their modification by polar groups, the van der Waals volume and molecular weight of the polymer, the concentration and form of the nanoparticles has been taken into account. The dependencies of T_f on the nanoparticle radius, their concentrations, number of polar groups grafted to the nanoparticle surface are plotted. The design scheme is computerized and included as a separate option into computer programs "Cascade" (INEOS RAS).
