熱電薄膜的形成方法

Abstract

一種熱電薄膜的形成方法，其包含先提供具有高分子熱電材料溶液、在具有高分子熱電材料溶液中添加銨鹽以形成第一混合溶液、將導電改質物添加於第一混合溶液中以形成第二混合溶液、移除第二混合溶液之水份以得到一固體以及烘烤此固體以形成具有多數個微結構之薄膜，該薄膜即為熱電薄膜，而其具有良好的導電性以及低導熱性。 A method for forming thermoelectric thin film is provided. The method includes a solution with polymer thermoelectric material therein which is provided. An ammonium is added into the solution with polymer thermoelectric material to form a first mixture. A conductive modified material is added into the first mixture to form a second mixture. A water or solvent is removed from the second mixture to form a solid. The solid is cured to form a thin film with a plurality of micro-structure therein, whereby the thin film is the theremoelectric thin film which includes a good conductivity and lower heat dissipation.
