奈米碳管-聚醯亞胺複合材料其屬於高分子導電材料,高分子本身並不導電,藉由加入導電的添加物填充於高分子中,以使其具導電性。本論文利用高分子單體聚合方法,製備多壁奈米碳管-聚醯亞胺奈米複合材料,研究後觀察到在電性上有顯著的增益,且發現此奈米複合材料其溫度-電阻的關係為半導體的性質,並在壓力-電阻上具有線性的關係,同時皆具有回覆性。
在我們測試出多壁奈米碳管-聚醯亞胺奈米複合材料薄膜具有上
述特性後,我們試圖做出微機電尺寸的感測器,在微型壓阻式感測器製程方面利用UV-LIGA製程技術,結構層部份使用SU-8 厚膜光阻製作微模,並對其烘烤溫度與時間加以控制,以多壁奈米碳管-聚醯亞胺奈米複合材料之薄膜為壓力訊號轉換成電阻訊號的材料。在以背向蝕刻玻璃基板形成凹槽(cavity)。最終感測器的測量結果也符合了壓力感測器的性質,所以此研究不僅可應用在導電材料上,還可以應用在或壓力感測器上。
Carbon Nanotube-polyimide composite is an extrinsically conducting polymer (ECP), the polymer can not conduct electricity, so it needs to add an electricity conducting filler to make it conduct electricity. In this study, Multi wall carbon nanotube - polyimide (MWNT-PI) can be fabricated to become Nano composites with the synthesis: in situ polymerization. Based on the observation, MWNT-PI can greatly improve in electric properties. It explains the synthesis can successfully promote the electric properties with low concentration of MWNT. In addition, the synthesis discovers that the temperature and resistance relationship of MWNT-PI has semi-conductor property. The pressure and resistance of this composite also have linear relationship and recoverable
property.
After finding above characteristic, we try to fabricate a MEMS size sensor. UV-LIGA process in the micro piezo-resistive pressure sensor process, we use MWNT-PI thin film to provide output electrical signal induced by input pressure disturbance , and the structural layer itself is defined by the micro mold, which consists of photoresist SU-8. It is crucial to control the temperature and time when it comes to the soft baking process for thick photoresist. Back etch glass substrate to get a cavity. In the end, the sensor testing answers to a pressure sensor. Therefore, the study has shown a valuable method which can be used in conductive polymer, and pressure sensor.
