聚苯胺/石墨烯複合薄膜之製備與應用於光電元件

導電高分子在1977年被發現以來，便是許多科學家不曾中斷的研究對象，在不同類型的導電聚合物中，聚苯胺因為它獨特的電化學特性和環境的穩定性，能夠供給商業應用的相當大的潛能，因此以聚苯胺為主的複合材料目前正吸引許多關注，原因是聚苯胺只要少量便能使聚合物混和導電且單體價格低廉。近年十分熱門的奈米碳材是石墨烯，它具有非常良好的各種物理性質，為了使其量產化並達到降低生產成本，不論學術界或業界，都有許多人員紛紛投入石墨烯製備的研究。本研究主要是藉由石墨烯極佳的導電性質與近乎透明的透光度兩項特性，期望維持聚苯胺的光學性質，並提升其導電能力，延伸其應用範疇。聚苯胺/(官能化)石墨烯複合薄膜製備完成後，經由SEM、FT-IR、UV-Vis、Four-Point-Probe、CV以及白光干涉儀等儀器進行化學性質和物理性質的分析，最後將薄膜應用在染敏電池中的電極，模擬太陽光系統，進行效率測試。經過儀器分析及效率測試後，證實石墨烯的添加的確增進聚苯胺的導電能力以及電化學表現，且聚苯胺/石墨烯複合薄膜的光電轉換效率最佳條件為0.3%，聚苯胺/官能化石墨烯複合薄膜光電轉換效率最佳條件則為0.5%，兩種薄膜皆能使未加入石墨烯的聚苯胺效率提升。

Since the discovery of conducting polymers in 1977, there’s lots of scientists keep doing the research in it. In different kind of conducting polymers, Polyaniline (PANI) got the special properties of electrochemistry and the stability of environment, which produces a wild potential of business application, so the composite material of main kind of PANI is attracting a lot of concern, and it’s because of there is only a few mass of aniline ,which can make the polymer mixture conduct, with cheep price of PANI. Graphene is one of the most famous carbon nano-materials these years, it has very good performance of physical properties. To bring it to mass production and lower the cost, there is lots of people get involved with the production research of graphene. This study is going to use the conduting properties with the properties of almost transparent, to maintain the optical properties of PANI, and enhance its conducting ability, extend the field of applications. After we produced PANI/(Functionalized-)Graphene, the SEM, FT-IR, UV-Vis, Four-Poing-Probe, Cyclic Voltammetry, and White Light Interferometers were used to analyze the chemical properties and physical properties, then, we used these composite films as an electrode of Dye-sensitized solar cells. Finally, I imitate the system of the sun optic to test its efficiency. After the production of PANI/(Func.-)Graphene Composite Film, we were sure that the addition of graphene could enhance the ability of conducting and performed well in electrochemistry test. And the best condition of opto-electronic conversion efficiency is 0.3%PANI/Graphene and 0.5%PANI/Func.-graphene, both kind of composite film could promote the efficiency much higher than pure PANI.
