Dynamics of electric charge transport and determination of the percolation insulator-to-metal transition in polyvinyl-pyrrolidone / nano-graphene platelet composites
Ch. Lampadaris, E. Sakellis, A. N. Papathanassiou
Polyvinyl-pyrrolidone (PVP) loaded with different fractions of dispersed nano-graphene platelets (NGP) were studied by Broadband Dielectric Spectroscopy in the frequency range from…
Exploring electrical conductivity within mesoscopic phases of semi-conducting PEDOT:PSS films by Broadband Dielectric Spectroscopy
A. N. Papathanassiou, I. Sakellis, J. Grammatikakis +2
Poly(3,4-ethylenedioxythiophene) : poly(styrene sulfonic acid (PEDOT:PSS), an optically transparent organic semi-conductor, constitutes a suspension of conducting PEDOT:PSS grains,…
Long aging time thermal degradation of the ac conductivity and complex permittivity of conducting polypyrrole
I. Sakellis, A. N. Papathanassiou, J. Grammatikakis
The modification of the ac conductivity and the complex permittivity of conducting polypyrrole was monitored throughout a two years thermal aging at 343K. Reduction of the cross-ov…
Self-diffusivity as a function of density and temperature in crystalline solids and compensating rules for self-diffusion parameters in Carbon - Subgroup crystals
A. N. Papathanassiou, I. Sakellis, J. Grammatikakis
The self-diffusion coefficient of crystalline solids as a function of density and temperature may derive from thermodynamics concepts and an earlier elastic thermodynamic point def…
