This study focuses on studying the effects of Electric Field of deferent
frequencies (20Hz – 3MHz), on RBCs after being irradiated by (690μW) of He-
Ne Laser, with testing some blood characteristics like osmotic fragility,
Conductivity and Dielectric constant.
A series of polymer blends are prepared by sequential mixing of epoxy resin
EP with polyurethane PU. The effect of different amount of polyurethane 10%,
20%and 30% wt fraction on conduction and dielectric relaxation has been
reported. It was found
that all blends showed three activation energies (Eac) at
all frequencies, and the glass transition temperature (Tg) was increased with
PU wt fraction. The exponent s values were estimated to be less than unity for
all blends. Cole-Cole diagram was used to evaluate the polarizability (α),
molecular relaxation time (τ) and optical dielectric constant (εOP). The
thermodynamic parameters also determined, the result showed that the Gibbs
free energy of activation (ΔG) and enthalpy (ΔH) are high for all blends.
