複合膠態高分子電解質及電化學聚合 3-己基噻吩之研究
An Investigation of Composite Gel Polymer Electrolyte & Electrochemical Polymerization of 3-Hexylthiophene
摘要
奈米複合材料所添加的蒙特土須逹到剝離，才能使物性逹到最佳的狀態。本實驗首先利用自由基不終止聚合反應，合成出 4-(N,N-Diethyldithiocarbamylmethyl)benzyltrimethyl ammonium bromide作為我們蒙特土(pk-802)的改質劑，並加入壓克力酸聚合使蒙特土達到剝離的狀態，最後再添加至不同之高分子中(nylon 6 & nylon 66)使之成為奈米複合材料並研究其機械及熱性質。隨後發現在添加至膠態PVC電解質中亦可提昇其離子導電度及降低熱膨脹係數，應用在鋰離子電池可充份增強效能。 共軛高分子具導電及發光之特性，而且polythiophene因其電子的特性跟熱穩定性使其成為導電高分子中重要的代表。本實驗藉由改變polythiophene的結構，導入-C6H13成為thiophene的側鏈基，以電化學聚合法使得3-HT成為P3-HT，再經由FT-IR以及NMR鑑定聚合成功與否，最終再測量其離子導電度發現比化學聚合法高出甚多。
並列摘要
Nanocomposites of clay/Nylon 6 and clay/Nylon 66 are studied in this research. The clay are exfoliated by acrylic acid living free radical polymerization. The exfoliated nanocomposites are obtained with clay contents ranging from 1 wt % to 10 wt %.The tensile strength and glass transition temperature increase significantly after adding the clay. Furthermore, we found the addition of clay into gel polymer electrolyte is also helpful to enhance the electrical & thermal behavior. The electrochromic conducting poly(3-hexylthiophene) film is prepared by electrochemical polymerization of 3-hexylthiophene in BFEE as the electrolyte in different concentrations of monomers , electrolytes and current densities. Their physical properties were characterized by FT-IR, UV. The morphology is studied by XRD. From the results of experiments, the electrochemical polymerization has the extraordinary physical properties. It is found that the thin film possesses ionic conductivity.
