以羥基封端之苯胺三聚體合成主鏈具電活性之聚酯材料性質分析與防腐蝕研究
Preparation, Characterization and Anticorrosion Studies of Hydroxyl-terminated Aniline Trimer Based Electroactive Polyester
摘要
本研究將羥基封端的苯胺三聚體導入聚酯高分子中，成功的合成出具電活性的聚酯材料，並有效的應用於金屬防腐蝕上。 首先利用對苯二胺與酚以氧化偶合法合成出羥基封端的苯胺三聚體，並以減弱全反射傅利葉轉換紅外線光譜儀（ATR-FTIR）、 液態核磁共振儀（1H-NMR）及液相層析質譜儀（LC-MS）進行結構鑑定。接著將羥基封端的苯胺三聚體與癸二醯氯（sebacoyl chloride）進行聚縮合反應，合成出具電活性的聚酯材料，以減弱全反射傅利葉轉換紅外線光譜儀（ATR-FTIR）、 液態核磁共振儀（1H-NMR）及凝膠滲透層析儀（GPC）進行結構鑑定。再利用循環伏特安培儀（CV）確認合成出的電活性聚酯材料具有氧化還原能力。 同時，本研究亦利用對苯二酚（hydroquinone）與癸二醯氯合成出非電活性的聚酯材料，將其與電活性的聚酯材料進行熱穩定性、防腐蝕及電化學阻抗分析比較。結果顯示電活性的聚酯材料不論是在熱穩定性、防腐蝕能力及電化學阻抗上，皆比非電活性的聚酯材料來得佳。

In this research, electroactive polyester containing hydroxyl-capped aniline trimer for anticorrosion is synthesized for the first time. Hydroxyl-terminated aniline was synthesized by carrying out oxidative coupling reactions between p-phenylenediamine and phenol, after which it was structural characterized by ATR-FTIR, 1H-NMR and LC-MS. Electroactive polyester then was prepared by polymerizing hydroxyl-capped aniline and sebacoyl chloride. According to series characterization including ATR-FTIR, 1H-NMR and GPC, along with cyclic voltammetry (CV), findings verified the chemical structures and its redox behavior of this electroactive polyester. In addition, the non-electroactive polyester was also synthesized and characterized for control experiments. It was found that the electroactive polyester has enhanced thermal stability, corrosion protection, and electrochemical impedance ability when compared to the non-electroactive polyester.
