Viscoelastic Effects on Molecular Dynamics of Dielectric Probes in Polymer Matrices

Viscoelastic effects of the matrix polymer on molecular dynamics dielectric probes were examined using generalized Langevin equation, which was derived to include retardation effect viscous force. By solving we successfully obtained universal relationship between complex relaxation modulus and spectrum probe. When viscoelastic properties are assumed be viscous, is described with Debye function. On other hand, if they supposed a power-law type spectrum, found Cole-Cole The proposed method applied previous study low-mass probe in polystyrene matrix. estimated effective close power-law-type relaxation. present provides new microrheological estimate nanometer size.
