本研究之目的是以電化學雙脈衝電位法來製備聚苯胺/三氧化鎢 複合材料， 希望藉由改變不同電化學脈衝聚合頻率以來尋求最佳合成條件， 使複合材料於可見光吸收範圍內有較佳的吸收度及較快的著色/去色應答時間。 由實驗結果分析得知，在低聚合頻率下較有利於聚苯胺的生成， 在高聚合頻率下則較易生成三氧化鎢於複合材料中， 然而在多層複合材料結構中的三氧化鎢薄膜較難生成， 且複合材料的吸收度變化情形卻有一定的範圍限制， 關鍵可能在於聚苯胺層與三氧化鎢層的配合以及導電度的影響等。
另一研究之目的主要是希望藉由控制不同苯胺(aniline)與甲苯胺(o-toluidine)單體含量比例量測其電變色性質， 以期能於可見光吸收範圍內有較佳的電變色性質， 並且比較不同組成對著色-去色應答時間的影響。 由實驗結果分析得知， 隨著苯胺單體在反應物中的含量越多， 共聚物的應答時間越久， 然而苯胺單體含量在50 %以下時， 苯胺單體在反應物中所佔比例25 %、33 %的共聚物去色/著色應答速率卻比50 %苯胺單體含量之共聚物來的慢。 此外由苯胺-甲苯胺共聚物的表面型態分析觀察得知，反應物中苯胺單體含量越多， 共聚物表面型態的顆粒越小， 並且較為接近纖維狀的結構且分佈較密集， 聚甲苯胺顆粒分佈則較稀疏且顆粒較大呈現泥狀， 共聚物顆粒分佈與大小則介於聚苯胺、聚甲苯胺之間。

Tungstic oxide/polyaniline composite films were prepared by a double-pulse electrodeposition technique. The experimental results revealed that polyaniline deposition efficiency is very high at lower frequencies, on the contrary, WO3 deposition efficiency is high at higher frequencies. In general, polymerization of aniline is faster than the deposition of tungsten trioxide at all frequencies. The change of absorbance upon coloration or discoloration process. It may be due to the conductivities of WO3 layers.
Poly(aniline-co-o-toluidine) copolymers, were prepared in aqueous solution by electrochemical method. The ratio of the two monomers in the solution has a great influence on the copolymerization process and the electrochemical behavior of the copolymers. The characterization of copolymer has been carried out using electrochemical and spectroscopic methods, and their properties were compared with those of homopolymers, polyaniline, and poly(o-toluidine). The experimental results revealed that the response time of copolymer becomes longer as the ratio of aniline in the aqueous solution increases. However, when the ratios of aniline in the aqueous solution are below 50%, the color/discolor response rate is slower than that of the copolymer synthesized in the aqueous solution containing 50% aniline. Besides, the morphology of poly(aniline-co-o-toluidine) showed that, when the content of aniline in the aqueous solution is larger, the particle size is smaller.
