碩士 === 國立臺北科技大學 === 化學工程研究所 === 100 === 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.
