to polycation and polyanion solutions repeatedly to transfer monolayers of these polyelectrolytes for every exposure a one mg ml solution of poly diallyl dimethyl ammonium chloride pdac at ph 2 5 was used as the polycation while approximately a one mg ml solution of sps pa at ph 2 5 was used as the polyanion the glass slide was exposed to each polyelectrolyte solution for 10 minutes and washed with water at the same ph 2 5 to remove the unbound polymer from the surface this process was repeated to obtain the desired number of layers 0062 fig7 a and 7 b show the visible absorption spectra of a film of fifty bilayers wherein pdac layers alternate with sps pa layers under various ph conditions as shown in the figures the multilayer film exhibited similar redox behavior as was observed previously with the solution absorption spectra this result confirmed that facile electrostatic deposition was reasible with the sps pa polymer complex and that the electrical activity was maintained after deposition in addition multilayer and bulk films were prepared on indium tin oxide ito slides and four point probe conductivity measurements were taken the results showed polymer complex conductivities in the range of 10 u2212 3 to 10.
