Prescriptions for manganese dioxide activated conducting polymeric composit
es have been elaborated. The investigated composites were made from a polye
thylene/vinyl acetate base (Elvax 450 from DuPont) and highly conducting ca
rbon black. The composite material was admired with manganese dioxide activ
ated graphite. Gravimetric, galvanostatic, potentiodynamic and impedance in
vestigations have been carried out of composite polymeric electrodes. It ha
s been shown that the presence of manganese dioxide in the composite improv
es the potential stability and decreases the oxygen evolution process resis
tance. An addition of manganese dioxide decreases the anodic consumption of
the polymeric composite. The relation of the current density function of t
he content of manganese dioxide modified graphite has been determined.
