Title A Continuum-Molecular Model of Oriented Polymer Region Formation in Elastomer Nanocomposite
Author(s) A.L. Svistkov (Institute of Continuous Media Mechanics, Ural Branch of Russian Academy of Sciences, Akad. Koroleva 1, Perm, 614013 Russia, svistkov@icmm.ru)
Abstract An approach for constructing a continuum-molecular model of a polymer material is proposed. The approach has the following advantages. It combines the convenience of dealing with the continuum representation, which permits numerically analyzing complicated processes at the nanolevel with the characteristic time measured in minutes. In addition, the model contains molecular representations which permit calculating the continuum properties with the specific features of interaction between links of molecular chains taken into account. Moreover, the state of the material can be inhomogeneous at the scale level that is several times greater than the dimension of a single link of the polymer chain.

One of the possible explanations of the process of formation of nanolayers of a polymer with specific properties is also proposed. It is shown that, as a result of interaction between polymer chain links, the influence is transferred from oriented regions to unoriented ones, which results in the growth of an oriented nanolayer on the surface of the active filler.
Keywords continuum model, nanocomposite, nonequilibrium state, layer, filler, orientation, polymer chains
