摘要註:	本研究第一部分以摻氮石墨烯 (NDG) /二氧化鈦 (TiO2) 奈米粒子修飾ITO電極，透過電化學法沉積3-甲基噻吩 (3-methylthiophene， 3MT) 於NDG-TiO2薄膜上，形成聚(3-甲基噻吩) (poly(3-methylthiophene)， P3MT) 複合材料 (P3MT/NDG/TiO2) 之電致變色元件電極。與ITO裸電極比較，NDG與多孔奈米TiO2層的插入明顯地提高了電致變色元件的光學對比度 (ΔT%)，其光學對比度從41% 提高到了70%。由實驗結果得知，相較於ITO裸電極在進行元件100圈 (4000 s) 操作後只能維持於元件初始光學對比度的70%， P3MT/NDG/TiO2複合電極之光學對比度在元件100圈 (4000 s) 操作後還可維持在原本的90%上下。此結果顯示，電致變色元件可藉由NDG與多孔奈米TiO2層的插入改善其穩定性，並且證明導電高分子/NDG/TiO2複合電極非常適合運用在電致變色元件上，以提升其效能及穩定性。與第一部分比較，第二部分是於1 M HCl水溶液環境中，以2,5-二甲氧苯胺 (2,5-dimethoxyaniline， DMA) 和N-[3-(三甲氧基矽基)丙基]苯胺兩單體不同的組成比例混合後加入TiO2奈米粒子，再以循環伏安法沉積P(TMSPA-co-DMA)-TiO2薄膜於ITO玻璃上作為電致變色元件之電極。接著由光譜電化學法 (in-situ UV-visible spectrochronoamperometric) 對元件進行光學對比度與穩定性的測試，其實驗結果顯示，TiO2奈米粒子的摻入改善了p(TMSPA-co-DMA) 薄膜於ITO電極的附著性，同時也抑制了在電化學聚合過程中，TMSPA與ITO電極間因締合/縮合效應形成的網狀結構，此結果可加速p(TMSPA-co-DMA)共聚物於ITO電極上的沉積速率，同時也改善了p(TMSPA-co-DMA)電致變色元件的穩定性。 Nitrogen-doped graphene (NDG)/titanium dioxide (TiO2) nanoparticles were coated on indium tin oxide (ITO) glass substrates to fabricate NDG-TiO2 nanocomposite electrodes. 3-methylthiophene (3MT) was electrochemically deposited on the NDG-TiO2 films to form poly(3-methylthiophene) (P3MT/NDG/TiO2) composite electrochromic electrodes. The introduction of NDG and TiO2 mesoporous films significantly increased the initial maximum optical contrast (ΔT%) to 70 % as compared 41 % of pure ITO electrodes， whereas the P3MT/NDG/TiO2 composite electrodes enhanced the adhesion of P3MT polymers to the NDG/TiO2/ITO substrate， thereby increasing the long-term stability of the corresponding electrochromic devices. After the stability test of 100 cycles, experimental results reveal that P3MT/NDG/TiO2 composite electrodes retained up to 90 % of ΔT%， relative to 70 % remaining ΔT% of pure ITO electrodes. This illustrates the enhanced long-term stability achieved through the introduction of a NDG-TiO2 nanocomposite films in electrochromic devices， and shown that conductive polymer/NDG/TiO2 composite electrodes are well suited to electrochromic devices for the promotion of performance and stability.In comparision to previous part， TiO2 nanoparticle was combined with 2,5-dimethoxyaniline (DMA) and 3-trimethoxysilanyl-propyl-N- aniline (TMSPA) in 1 M HCl aqueous solution for different feed ratios of TMSPA， then deposited P(TMSPA-co-DMA)-TiO2 film on ITO glass using cyclic voltammetry and used as an electrode in an electrochromic. The optical contrast (ΔT%) and long-term stability of the device were determined by in-situ UV-visible spectrochronoamperometric studies. Experimental results reveal the introduction of TiO2 nanoparticle enhanced the adhesion of P(TMSPA-co-DMA) copolymer as compared a bare ITO substrate also we found that this system can inhibit the association/condensation effect of TMSPA network on ITO substrate during electrochemical copolymerization. This system speeds up the deposition rate of P(TMSPA-co-DMA) copolymer on the ITO substrate and enhanced long-term stability of P(TMSPA-co-DMA) electrochromic device.
