【摘要】 近年来，有序介孔／微孔结构薄膜材料在催化、传感器、分离膜、微反应器、细胞培养基材、微电极、光子晶体，生物医学等方面得到广泛应用，成为纳米技术领域的研究热点之一。材料表面的微制作将成为产生新的功能界面的重要手段。导电聚合物及其与之复合材料、发光材料等功能聚合物材料的图案化研究现已引起人们广泛的兴趣和高度的重视。 本文采用水辅助方法，使用4-十二烷基苯磺酸（DBSA）质子酸掺杂的聚苯胺（PANI-DBSA）、无机磁性Fe₃O₄纳米粒子和PANI-DBSA复合材料（PANI-DBSA／Fe₃O₄）、聚[2-甲氧基-5-（2′-乙烯基-己氧基）对苯乙炔]（MEH-PPV）发光材料，在高湿度条件下，以水为模板，成功制备了蜂窝状有序多孔薄膜，并对其电学、磁学、光学等性质进行了表征。 1．首次采用水辅助方法制备PANI-DBSA蜂窝状有序多孔薄膜。通过控制溶液的浓度和环境的相对湿度，得到了不同结构的有序多孔薄膜。分吉林大学博士学位论文析认为，形成蜂窝状有序多孔薄膜的驱动力是控制短程的毛细管力和长程的回流作用力。并证实得到的R气Nl一DBSA蜂窝状有序多孔薄膜具有良好的电学性质，即具有有机半导体特性。有望在这种具有导电性聚合物的有序孔薄膜内进行组装，以制备异质复合体，以期在功能器件方面得到应用。 2.采用水辅助方法制备了RANI一DBS户以Fe304复合材料的蜂窝状有序多孔薄膜。分别通过原子力显微镜（AFM）和透射电镜（TEM）对形成的复合材料薄膜的形貌进行了表征，证实此方法可以制备出由R气Nl一DBSA/Fe3仇复合材料的蜂窝状多孔薄膜，且Fe3仇均匀分布在EANI一DBSA中。这种薄膜有望在电磁屏蔽等方面得到应用。 3，MEH一PPV由于具有良好的荧光特性引起了人们方法的研究兴趣。我们采用水辅助方法制备出蜂窝状多孔结构薄膜，并通过AFM和共聚焦显微镜等对其形貌进行了表征。并结合其荧光光谱，证实了采用水辅助方法制备出的蜂窝状多孔结构薄膜具有良好的光学性质。更多还原

【Abstract】 Ordered mesoporous / microprous solids are of interest in areas such as catalysis, sensors, size- and shape-selective separation media, adsorbents and scaffolds for composite materials synthesis. Therefore, microfabrication will be a key technology in providing novel interfacial functions on material surfaces. Conductive polymers and their hybrid materials have aroused many interests, and their ordered structured films are of paramount importance.In this paper, we have successfully fabricated the honeycomb structured films of PANI-DBSA, PANI-DBSA/FeO MEH-PPV by a simply self-assembly method in moisture atmosphere. And their conductive, magnetic, and photonic properties are investigated in detail, respectively.1. 4 - dodecylbenzenesulfonic acid (DBSA) - doped polyaniline (PANI) honeycomb structured film is successfully fabricated by water assisted self-assembly method for the first time. In the humidity atmosphere, ordered honeycomb structure can be well fabricated. By controlling the relative humidity in the atmosphere and concentration of the conducting polymer respectively, different morphology of the honeycomb structure can be obtained. The driving force of this self-assembly procedure is capillary force and the water droplet plays the role as template. Furthermore, the honeycomb structured film of PANI-DBSA is proved to be electro-active and shows the semi-conducting properties in the appropriate doping state. The structures fabricated are expected to be attractive candidates to manipulate photons in 3D crystals. The ability to make 3D ordered macro-porous structures with conducting polymers should lead to new applications in electronic and electrochromic devices.2. Water assisted method is applied to fabricated honeycomb structured PANI-DBSA/Fe3O4 film. The morphology is characterized by the Atomic Force Microscopy (AFM) and Transmission Electronic Microscopy (TEM). PANI-DBSA can be clearly indexed on the wall of the pore through the AFM observation, while the magnetic particles can be well observed from the TEM images with the uniform distribution.3. Poly(2-methoxy-5-(2’ -ethyl-hexloxy)-p-phenylene-vinylene)(MEH-PPV) is proved to be a very interesting material because of its high photoluminescence (PL) efficiency. Ordered honeycomb structure film of MEH-PPV is obtained by self-assembly method through water droplet template, the morphologies of both atomic force microscope (AFM) andconfocal fluorescent microscope are given, and the fluorescent properties are studied in detail. It was found by fluorescence spectra that the honeycomb structure film from water-assisted fabrication keeps good photoluminescence.更多还原
