dc.description.abstract | 近年來,高分子材料相關之研究蓬勃發展,其中以有機共軛高分子最受矚目,因為其具有良好的結晶性、光電特性以及高分子本身自組裝之特性,目前已被廣泛應用於有機場效電晶體(Organic field-effect transistors, OFETs)、生物傳感器(Biosensors)和共軛高分子太陽能電池(Conjugated polymer solar cells, CPSC)等元件中。在各式有機共軛高分子中,又以聚(3-己基噻吩)(Poly(3-hexylthiophene), P3HT)之研究最為熱門,因其具有絕佳的化學穩定性、高性能且製備簡單等優點,充滿應用潛力。雖然目前已有許多針對聚(3-己基噻吩)之研究,但在如何控制其形貌與特性仍是一大挑戰。本研究以晶鬚法(Whisker method)的技術為基礎製備聚(3-己基噻吩)奈米線,並將此奈米線應用於薄膜與粒子等不同形貌之材料,除此之外,更針對聚(3-己基噻吩)奈米線的形貌結構以及光物理性質做高解析鑑定。 本論文之實驗結果共分三個部分。第一部分我們成功製備含有聚(3-己基噻吩)奈米線之薄膜並探討聚(3-己基噻吩)的去潤濕(Dewetting)現象對薄膜形貌之影響,以及聚(3-己基噻吩)奈米線對去潤濕現象之影響。在第二部分嘗試結合晶鬚法與微乳液法(Mini-emulsion),成功製備含結晶性的聚(3-己基噻吩)奈米線之微米粒子,並探討聚(3-己基噻吩)奈米線對微米粒子特性之影響。最後一部分與中研院合作,利用高解析顯微鏡量測單根奈米線結晶行為以及光電性質。本論文不僅提出聚(3-己基噻吩)奈米線應用於薄膜與粒子材料的新穎製備方法,同時也對聚(3-己基噻吩)奈米線的分子結構排列提供更深層的了解。 | zh_TW |
dc.description.abstract | Poly(3-hexylthiophene) (P3HT), the benchmark polymer of the low-bandgap conjugated polymers, has been extensively studied because of its attractive properties such as high optoelectronic performance, chemical stability, and solution processability. Therefore, it has great potential in applications such as organic photovoltaic devices (OPV), biosensors, and organic field-effect transistors (OFETs). Thin films of P3HT have been widely investigated, but the dewetting phenomena and morphology control of P3HT are still not well-understood. In this thesis, P3HT nanowires are fabricated by the whisker method and properties of films and wires in various conditions are discussed. The experimental results are separated into three parts. In the first part, we study the dewetting phenomena of P3HT films and wires by controlling the spin-coating rates, substrates, and solvent annealing times. It can provide useful information of spin-coated P3HT films for device fabrications. In the second part, we successfully prepare P3HT microspheres with high crystallinities by combining the whisker method and the emulsion method. Such P3HT microspheres may have more potential applications than those prepared only using the emulsion method. In the last part, we cooperate with Prof. Chi Chen’s group in Academia Sinica to study the crystallization behavior and photophysical properties of single P3HT nanowires using HR-AFM and Photoluminescence. | en_US |
