    摘要: 近年來金屬氧化物奈米粒子的合成,並以這些奈米粒子結合高分子製備複合薄膜已被廣泛研究。這些奈米粒子中,透明導電氧化物,特別是銦錫氧化物奈米粒子特別令人感到興趣。溶液法合成銦錫氧化物奈米粒子已開始被研究,並具備一些優點,如簡單的操作程序、低的設備成本、可容易調整實驗參數。除球狀的奈米粒子,銦錫氧化物奈米柱、奈米線及奈米方塊粒子已被合成。雖然許多關於利用高分子為穩定劑與結構導向劑合成無機奈米粒子的報告已被發表,但極少數著重於對銦錫氧化物奈米粒子大小及形狀的控制。 在本研究計畫的第一年,將以聚電解質為穩定劑與結構導向劑,以共沈澱法合成不同形狀與大小的銦錫氧化物奈米粒子。研究聚電解質對銦錫氧化物粒子的型態影響與結構導向機制,並探討不同形狀及大小的銦錫氧化物奈米粒子的電學與光學性質。目前的研究中,由銦錫水合物轉成的銦錫氧化物奈米條已經被合成,水合物前驅物是藉由聚電解質為穩定劑與結構導向劑以共沈澱法製備。計畫使用多種聚電解質進行更多及詳盡的研究。 在本研究計畫的第二年,將在塑膠基板上製備銦錫氧化物透明導電膜,以及近紅外光遮蔽塗膜的製備。第一個研究中,必須使用低溫(< 130 ºC)的塗佈製程,一維的銦錫氧化物奈米條必須水平緊密的堆積或者分散在導電高分子中。逐層堆疊技術也會被考慮使用來製備導電紙,結合銦錫氧化物奈米條與聚電解質形成多層結構。第二個研究中,塗膜對可見光須有良好的穿透性,極小的銦錫氧化物奈米粒子必須獨立均勻分散在透明的有機樹脂或高分子中。 在本研究計畫的第三年,將以水/溶劑熱合成法及單鍋加熱法合成銦錫氧化物奈米粒子,研究聚電解質對銦錫氧化物粒子的型態影響。將以不同的反應條件合成銦錫氧化物奈米粒子,分析其形狀、大小、電學與光學性質,並用以製備塑膠基板上的銦錫氧化物透明導電膜,以及近紅外光遮蔽塗膜。
    In recent years synthesis of metal-oxide nanoparticles and preparation of composite thin films from these nanoparticles with various polymers have been widely studied. Among these nanoparticles, transparent conducting oxide (TCO), especially indium-tin oxide (ITO), nanoparticles are of particular interest. Solution methods to synthesize ITO nanoparticles have been investigated and have some advantages, such as the simple operating process, the low costs for the equipments, and the easily adjustable experimental parameters. Expect spherical nanoparticles, ITO nanorods, nanowires, and nanocubic particles have been synthesized. Although large number of reports on inorganic nanoparticles synthesized using polymers as stabilizers or structure-directing agents have been conducted, little research has focused on the size or shape control of ITO nanoparticles. In the first year of this research proposal, polyelectrolytes as the stabilizer and structure-directing agent will be used to synthesize ITO nanoparticles with various shapes and sizes via co-precipitation. The effects of polyelectrolytes on morphology of the synthesized particles and the mechanism of structure- directing will be investigated. Besides, the electrical and optical properties of the synthesized ITO nanoparticles with different shapes and sizes will be investigated. In the present work, ITO nanostrips from the indium-tin hydroxide have been synthesized. The hydroxide precursors were prepared using a co-precipitation method, in which a polyelectrolyte was employed both as the stabilizer and structure-directing agent. More and detailed studies using various polyelectrolytes will be executed. In the second year of this research proposal, transparent conducting thin films on the plastic substrates and near-infrared (NIR) shielding coated films will be prepared. In the first research, low temperature (< 130 ºC) coating process is necessary, and one dimensional ITO nanostrips have to be horizontally close piled up or dispersed in the conducting polymers. Layer-by-layer (LBL) technology will be also considered to prepare conducting papers, in which the multi-layers combine ITO nanostrips with polyelectrolytes. In the second research, the coated films have to be good transparency to visible light, and very small ITO nanoparticles have to be independent and well-dispersed in the transparent organic resins or polymers. In the third year of this research proposal, hydrothermal/solvothermal synthesis and one-pot heating process will be used to synthesize ITO nanoparticles. The effects of polyelectrolytes on morphology of the synthesized particles will be investigated. ITO nanoparticles will be synthesized using various reaction parameters, and their shape and size as well as electrical and optical properties will be characterized. Transparent conducting thin films on the plastic substrates and near-infrared shielding coated films will be prepared using these synthesized nanoparticles.
