Studies on Polymeric-Inorganic Functional Materials-Novel

东京农业技术大学（TUAT）和朱拉隆功大学（CU）多年来一直密切开展学术交流活动。作为两所大学的研究合作项目之一，本项目旨在利用从泰国丰富的动植物中提取的各种化学物质，利用先进的聚合物-无机杂化材料及其合成技术，制成微颗粒、微胶囊、电子器件等微型器件。在三年的时间里，在非线性有机光学器件、聚合物微球和微胶囊领域取得了以下实验成果：从巨型海鲈的皮肤和鳞片中提取的光致发光染料以及从椰子壳肉中提取的液晶被证明是电子显示器的重要原料。鉴定了从泰国植物中提取的具有特殊药用活性的萜类和生物碱，并成功地包封了实用剂量。采用光氧化催化剂和光散射填料成功封装了锐钛矿型二氧化钛。将高度对水分敏感的路易斯酸（如氯化铝）微胶囊化在有机介质中，同时保持其活性。采用玻璃膜乳化技术合成了中空聚合物微球，并将其应用于吸油剂。总之，已经确定了若干可行的途径，通过将泰国自然资源转化为更容易操纵的形式来利用它们。

Tokyo University of Agriculture and Technology (TUAT) and Chulalongkorn University (CU) have been closely tied with academic exchange activities for years. As one of the research cooperations between the two universities, this project was organized in order to utilize various chemicals extracted from abundant florae and faunae in Thailand by fabricating into tiny devices such as microparticles, microcapsules, electronic devices, and so on, using sophisticated polymer-inorganic hybrid materials and their synthetic techniques. In three years terms, the following experimental accomplishments were obtained in the fields of non-linear organic optical devices, polymeric microspheres, and microcapsules.1. Photoluminescent dyes extracted from the skin and scales of giant sea perch, and liquid crystals from coconut shell-meat were proved to be prominent raw materials for electronic displays.2. Terpenoids and alkaloids extracted from Thai plants which yielded particular medicinal activities were identified and successfully encapsulated for practical dosage.3. Anatase type titanium dioxide was successfully encapsulated for use of photooxidation catalyst and light scattering fillers.4. Microencapsulation of highly moisture-sensitive Lewis acids such as aluminum chloride was encapsulated in organic media while retaining its activity.5. Hollow polymeric microspheres were synthesized using glass membrane emulsification technique, and applied for oil absorbent.In conclusion, several feasible routes to utilize Thai natural resources by transforming them into the forms easier to manipulate have been established.
