In the search to find materials with high conductivity, high electrochemical stability, recently the graphene family is presented as one promising advanced material. Nevertheless, are existing different challenges for avoid the restacks between their sheets and presented a semiconducting behavior due to their interaction with the medium, etc. Is for this what hybrids materials based on graphene could also offer great advantages for different applications for energy as for example electrochemical capacitors, solar cells, etc.

 In this work was obtained hybrid materials based on GO/ PMo12/conducting polymer, conducting polymer/PMo12 and GO/ PMo12. The OG was obtained by Brodie method and thermally reduced. The method that was used for polymerization of monomers (pyrrole and aniline) was interfacial. For the cases of conductive polymer/PMo12, the ratio was 16.6% monomer and 83.4 % of PMo12 of weight while GO/ PMo12/conducting polymer this ration was of 10, 50 and 40% in weight, respectively.

 All materials obtained were characterized by DRX, SEM, Raman and FTIR; and for evaluate their electrochemical behavior, the materials was deposited on cloth carbon and characterized by voltamperometry cyclic using a cell with three electrodes and H2SO4 1M at different scan rates; also was evaluated stability cyclic at 1000 cycles.
