固態電解質比液態電解質在電容器、電池及其他相關的電子元件中，有較多的優點，這是我們所知道的。導電高分子可利用有機酸的摻雜(doping)而附予導電性，例如比聚比洛(PPy)，具有高頻(~1Mhz)低阻抗(~1Ω)及300℃以上的溫度穩定性，尤其可應用於現今電子工業的表面黏著技術(SMT)。
The advantage of solid over liquid electrolyte in capacitors, batteries and other electrically related devices at high frequency has been well known. Conductive polymer having organic acid dopants such as polypyrrole (PPy) is considered to be the best candidate. Especially in order to meet the requirements for new trend in surface mount technology (SMT) in electronic industry today, PPy has shown its edge to have a high temperature resistance above 300℃ and a low impedance (~1Ω ) at high frequency(~1 Mhz).
In this paper we have compared two approaches of slightly different treatments in coating of PPy layer on Al2O3 substrate of nano-scale. The first approach is the adoption of a proprietary mixture of polyaniline (PAn's) and PPy; the other is a direct coating of PPy with an anionic surfactant electrolyte. It was shown that while the effectiveness of the conductive solid electrolyte plays a key role, the quality or the fine
