本論文分成三個研究主題來討論,主要利用循環伏安法與透光薄層電化學法(optically transparent thin-layer electrode, OTTLE)來分析與討論聚苯胺及聚二苯胺修飾在Indium-Tin Oxide(ITO)的變化。第一部份將Polyaniline (PANI)、PAA/PANI、PANI+clay修飾在ITO導電玻璃上,並將此三種修飾電極分別置入pH=3.0-9.0不同的緩衝溶液中偵測,觀察其穩定度。 第二部份研究二苯胺電化學氧化後的產物,利用電化學與光譜電化學觀察diphenylamine(DPA)、N,N’-diphenylbenzidine(DPB)、N,N,N’-triphenyl-p-phenylenediamine(TPPD)、di-p-tolylamine(DTA),將氧化電位與光譜波長相互比較,推測二苯胺氧化後的物質可能為N,N’-diphenylbenzidine(DPB)。 第三部份將diphenylamine(DPA)利用電化學方法在ITO導電玻璃上聚合成polydiphenylamine(PDPA),製作PDPA、PAA/PDPA、PDPA+clay等三種修飾電極。將此三種修飾電極分別置入pH=1.0-9.0不同的緩衝溶液中偵測,觀察其穩定度。
This thesis included three topics. By using CV and OTTLE, polyaniline(PANI) and polydiphenylamine(PDPA) coating on ITO have been investigated. The first one has been concerned with PANI、PAA/PANI and PANI+clay coating on ITO with using pH=3.0-9.0 buffer solution, respectively. The second topic was the electrochemical study of diphenylamine. By comparing with the oxidation potential and spectral wavelength of diphenylamine(DPA)、N,N’-diphenylbenzidine(DPB)、N,N,N’-triphenyl-p-phenylenediamine(TPPD) and di-p-tolylamine(DTA). The electrochemical product of DPA was DPB. The third topic was using electrochemical polymerization method to get PDPA、PAA/PDPA and PDPA+clay coating on ITO. With the different pH buffer solution, we could observed the stability of polymer film.
