氧化石墨烯-奈米銀和導電聚噻吩複合材料之研究

Studies on Graphene Oxide-Ag and Conductive Polythiophene Nano-Composites

指導教授 : 張淑美

摘要


本研究目標為製備石墨烯-奈米銀/聚二氧乙基噻吩-聚苯乙烯磺酸複合材料薄膜,使用氧化石墨烯吸引奈米銀前後和合成聚二氧乙基噻吩-聚苯乙烯磺酸進行混摻,探討對於複合材料薄膜的石墨烯分散以及導電度造成的影響。 聚噻吩衍生物使用自行合成二氧乙基噻吩單體(EDOT)與聚二氧乙基噻吩-聚苯乙烯磺酸(PEDOT:PSS)聚合之製備。 石墨烯進行兩部分表面改質,第一部分是利用Hummers method製備氧化石墨烯(Graphene Oxide,GO);第二部分是以奈米銀離子吸引氧化石墨烯再藉由化學還原的機制使奈米銀離子還原奈米銀和石墨烯。 使用氧化石墨烯吸引奈米銀前後和合成聚二氧乙基噻吩-聚苯乙烯磺酸進行混摻,探討對於複合材料薄膜的石墨烯分散度以及片電阻造成的影響。藉由核磁共振光譜(NMR)、傅立葉轉換紅外光譜儀(FT-IR)、熱重量分析儀(TGA)、紫外光/可見光光譜儀(UV-vis)、X-光粉末繞射儀(XRD)、拉曼光譜儀(Raman)、X-光光電子能譜儀(XPS)、原子力顯微鏡(AFM)、掃描式電子顯微鏡(SEM)、穿透式電子顯微鏡(TEM)、四點探針(Milliohmmeter)鑑定樣品之特性。

並列摘要


The aim of this study is to prepare graphene oxide-Ag /conductive poly (3-4ethylenedioxythiophene) nano-composites. We blend graphene oxide before and after the surface attractive of nano Ag and poly(3-4ethylenedioxythiophene) - polystyrene sulfonic acid that synthesized. The dispersion of graphene in composites and conductivity were tested and discussed. The polythiophene derivatives we synthesized are monomer 3-4ethylenedioxythiophene、poly(3-4ethylenedioxythiophene) -polystyrene sulfonic acid (PEDOT:PSS) polymer. There are two parts about the surface modification of graphene, the first part of the Hummers method oxidized graphene (GO) ; second part of the nano Ag ion attract mechanism by chemical reduction of graphene oxide to make nano Ag ions to restore nano Ag and graphene. We blend graphene oxide before and after the surface attractive of nano Ag and poly(3-4ethylenedioxythiophene) - polystyrene sulfonic acid that synthesized. The dispersion of graphene in composites and conductivity were tested and discussed.The products were characterized by NMR、FT-IR、TGA、UV-vis、XRD、Raman、XPS、AFM、SEM、TEM、Milliohmmeter identification of samples of characteristics.
