Abstract

A nanomaterials graphene and titanium oxide (TiO2) have been prepared and characterized by IR, atomic force microscopy (AFM) and  X-ray diffraction. The different thin films of mixed poly(vinyl alcohol) and polyacrylamide, polymers/nano TiO2 and polymers/ nano(graphene + titanium oxide) have been prepared and their electrical properties (real and imaginary electrical isolation constants and conductivity) were examined at different frequencies. A super capacitors based on polymer mixtures and polymers mixture with nanomaterials have been prepared and their voltages examined at charging and at different intervals of time (5, 10, 15 and 30 min and 1, 5, 10, 15 , 20 and 24 h). The best capacitor was of polymer mixture/nano(graphene + TiO2), which is attributed due to the good conductive properties of graphene.
