| Research Abstract |
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.
