Engineering Physics Annotation << Back THE THERMODYNAMICAL MODEL OF FORMATION MECHANISM OF INTERFACIAL REGIONS IN NANOCOMPOSITES POLYPROPYLENE/GLOBULAR NANOCARBON P.G. RIZVANOVA, G.M. MAGOMEDOV, G.V. KOZLOV An interfacial regions have higher modulus of elasticity in comparison with bulk polymer matrix and therefore they are reinforcing element of their structure, that requires thorough study of formation mechanism, structure and properties of these regions. Within the thermodynamic approach it has been shown that polymer adsorption on nanofiller particles is formation mechanism of interfacial regions in particulate-fi lled nanocomposites. A characteristics of both initial particles of nanofi ller (their mass) and aggregates of the indicated particles, obtained in process of nanocomposites production (density and surface structure) are served as parameters, controlling this process. The last factor can be characterized by fractal dimension of surface of particles aggregate. In this connection the methodics of determination of both size of particles aggregates of disperse nanofiller and fractal dimension of their surface. Knowledge of relative fraction of interfacial regions allows the theoretical estimation of reinforcement of particulate-filled nanocomposites, which corresponded well to experimental data. Key words: nanocomposite, globular nanocarbon, adsorption, interfacial regions, aggregation, fractal dimension. DOI: 10.25791/infizik.01.2019.389 Contacts: E-mail: i_dolbin@mail.ru Pp. 21-24.
