Abstract:
    As a result of the electrophilic protonation of a carboxyl group of dielectric polymethylmethacrylate (PMMA) with trifluoromethanesulfonic acid (CF<sub>3</sub>SO<sub>3</sub>H), a modified conducting polymer material was produced in the shape of a thin elastic lamina and a dense conductive gel, whose density was 1.26 g/cm<sup>3</sup>. These polymers conduct electricity, do not dissolve in either cold or warm water and are also resistant to weather conditions. Their conductivity in room temperature is 7.5·10<sup>-3</sup> Scm<sup>-1</sup> and it greatly increases above 154 K. Activation energy E<sub>a</sub> decreases with increasing temperature in the range 154 K – 300 K from 1.47 eV to 0.69 eV. The magnesium-polymer (Mg-Poly) cell is constructed with magnesium as the anode and conductive PMMA as the cathode and both electrodes are electrically connected with a polymer gel electrolyte. The rated voltage of this cell is 2.4 V.
