本文嘗試在低成本與簡單設備的條件下製作具有高功率因子的熱電薄膜，在三種導電高分子中選出具有較佳熱電性質的PEDOT:PSS做為基材,再分別將購買的碲化鉍粉末,化學法合成出來的碲化鉍粉末經由氯化氫處理，以及電化學沉積後分離的Bi-Se-Te粉末加入其中, 量測熱電性質。再從中選出具有最佳特性的P-type薄膜後與利用聚乙烯亞胺對奈米碳管改質過後得到的N-type薄膜嘗試做成元件,然而在材料的熱電特性與塊材相比仍有一段差距的情形下,還有很大的改善空間。

The main purpose of the research is that fabricating a thermoelectric film with a high value of Power Factor on the condition of low-cost and easy-make.At first,choosing the base material,PEDOT:PSS from three kinds of conductive polymers which has the best thermoelectric performance.Then blend with the following materials:Commercial Bi2Te3 powders,the Bi2Te3 nanopowders synthesized by chemical method,and the Bi-Se-Te powders made by electrochemical deposition.The same as the first step,choosing the P-type thin film which has the highest perpformance and combine with the N-type material:PEI-SWNT.Try to do a organic thermoelectric cooler device.However,thermoelecctric properties are not as good as bulk material,resulting in a efficiency of device still much room for improvement.
