Study OF Electrical Properties Of (PEO-PEG) ) and (PEO-PMMA) Blends.

Abstract

The study it includes the recording of the spectrum of electrical properties.The electrical properties include the measuring of the electrical conductivity,then calculate the molar conductivity and the degree of dissociation. for the blend solutions at the room temperature .These samples have been prepared in different weight concentrations (0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8 g/mL) % as solutions then the additives (PEG , PMMA ) added as (0.25 g ) and ( 0.5 g) respectively , also the samples prepared by liquids mixing method before and after adding (PEG ,PMMA) polymer.The electrical properties include the measuring of the electrical conductivity and then calculate the molar conductivity and the degree of dissociation. have been measured,. All those properties have been measured for two cases before and after addition at room temperature . The conductivity of pure polymer and its additives used in this work are increasing with the increase of the polymer concentration. After adding of the polymers to polyethylene oxide, the conductivity increases with the increasing of concentration for all additives , Noting the molar conductivity values decrease with increasing the molar concentration, note these values of the molar conductivity decrease after the addition of polymers, that dissociation values of the polymer decrease with increasing of concentrations
