Dielectric Dispersion and Molecular Interaction in Polymer (PVA)-Surfactant (SDS) mixtures using picosecond time domain reflectometry

The interaction between polymers and surfactants molecules in aqueous medium interaction has significant changes in dielectric dispersion and offer ascent to the development of affiliation structures. The correlation of interaction alters the ordering and interfacial properties. The dielectric portrayal study on relaxation and molecular interaction of in ternary blend of polymer and the surfactant viz. polyvinyl alcohol (PVA) and sodium dodecyl sulphate (SDS) in aqueous solutions focused on various concentrations at 298 K. The excess permittivity (εE), electrical conductivity (σ), free energy of activation (ΔF), dielectric relaxation (τ), Kirkwood correlation factor (geff) for relative concentrations of the ternary specimens considered. The hydrated micelles in PVA pivot as one unit in the viscous medium with critical changes in dielectric parameters by the blend constituents of SDS in the frequency range 10MHz to 30GHz. The estimations of geff acclimates relationship component of molecular interaction and parallel orientation of molecular ordering.
