A Study the Effect of ZrO3 on the Electrical and Mechanical Properties of ( PMMA - Cr2O3 )

Abstract

The polymers have many uses in industries. The addition of electrolytes to the polymers are produced a new materials use in many applications. Hence, in this paper study the effect of ZrO₃ on the electrical and mechanical properties of  PMMA - Cr₂O₃ with concentrations (1, 5, 10, 15, 20) % gm/ mole at room temperature. ZrO₃ was added to polymer with amount weight of (0, 3, 6, 9, 12) wt% added to the polymer. The mechanical properties were measured by using ultrasound technique with frequency (26kHz), show that the relaxation amplitude, relaxation time, velocity, as well as bulk modulus of polymer are increasing with the increment of ZrO₃ weight percentages. The compressibility of PMMA - Cr₂O₃ decreases with the increment of ZrO₃ weight percentages. The electrical properties measurement of PMMA - Cr₂O₃ show that the electrical conductivity is increased with increment of ZrO₃ weight percentages and both of molar conductivity and degree of dissociation are decreased with increment of  ZrO₃ weight percentages
