티타늄마드래스 소지에 PbO_2를 전착하는 과정에서 전해액에 여러 가지 산과 유기물질의 첨가는 PbO_2전착층의 물성에 큰 영향을 준다. XRD결과 β-PbO_2가 산성 전해액에서 전착되는 것을 확인하였다. 본 실험에서 사용된 첨가제 중 전해액에 sodium louryl sulfate를 첨가할때 산소과전압이 가장 높은 PbO_2가 전착되었으며 polyethylene glycol을 첨가할때는 염소과전압이 가장 낮은 PbO_2가 전착되었다. PbO_2의 산소과전압과 염소과전압은 PbO_2를 전착하는 동안 행하는 교반에 크게 의존한다. SEM결과 전착하는 동안 교만하지 않고 전착한 PbO_2결정이 교반하여 전착한 PbO_2보다 더욱 크다는 것을 관찰하였다. 또한 산성전해액에서 PbO_2를 전착할 경우, PbO_2결정 크기가 클수록 산소과전압은 커지며 PbO_2결정 크기가 작을수록 염소과전압은 낮아졌다. HClO_4의 존재하에서 PbO_2를 전착할 경우 560g/1 Pb(NO_3)_2, 65∼70℃, pH>1에서 최적의 전착전류효율을 나타내었다.

Addition of various acids or organic compounds to the electrolyte solution during the electrodeposition of PbO_2 on titanium madras substrate strongly affected performance of the deposited PbO_2 layer. Results of X-ray diffractometry ascertained that β-PbO_2 was deposited in acidic electrolyte. Among additives used in this experiment, PbO_2 with a high oxygen overvoltage was electrodeposited when sodium lauryl sulfate was added, and PbO_2 with a lower chlorine overvoltage was electrodeposited when polyethylene glycol was added to the electrolyte solution. The oxygen and chlorine overvoltage of PbO_2 was strongly dependent on the stirring provided during the electrodeposition experiment. It was observed by the SEM results that the PbO_2 grains deposited when stirring was not provided during the electrodeposition have larger than PbO_2 grains deposited by stirring. In the PbO_2 deposition under acidic electrolyte, the oxygen overvoltage increased with larger PbO_2 grains and the chlorine overvoltage decreased with smaller PbO_2 grains. The optimal current efficiency of PbO_2 in the presence of perchloric acid was observed at Pb(NO_3)_2, 560g/1, 65∼70℃, and pH>1.
