The Viscoelastic Coarse-Grained Dynamic Model of the Polymer Network with Embedded Rod-Like Particles. Relaxation Spectra and Mobility of Different Scales
The viscoelastic coarse‐grained dynamic model of a polymer network with rod‐like particles included into the network is considered. The rods are regularly distributed in the network. The entanglements of rods in a polymer network lead to quasielastic interactions between the rods and network fragmen...

| description | The viscoelastic coarse‐grained dynamic model of a polymer network with rod‐like particles included into the network is considered. The rods are regularly distributed in the network. The entanglements of rods in a polymer network lead to quasielastic interactions between the rods and network fragments. The structure of the relaxation spectrum is considered. The dependence of the relaxation properties of the network with included rods on the viscoelastic parameters of the network without rods, on the length and the friction of the rods are investigated at different strength of the interaction between rods and network fragments. The differences between collective types of relaxation of the rods and the network and localized motions of the rods on the background of immobile network fragments are discussed. The results of the theory are applied to the description of the rotational and translational motions of the rods appearing in dielectric relaxation, NMR and other phenomena. |
