Composite thermoelectric material formed by conductive polymer

The invention provides a composite thermoelectric material formed by a routine conductive polymer, and a pn-junction laminated thermoelectric conversion device. A p-type conductive layer of the composite thermoelectric material is obtained through mixing P3HT and PVDF. An n-type conductive layer of the composite thermoelectric material is obtained through mixing PANI and PVDF. A PVDF polymer insulating layer is arranged between the p-type conductive layer and the n-type conductive layer for insulating. The pn-junction laminated thermoelectric conversion device is prepared according to a spraying method. Furthermore simple preparation process and low cost are realized. 种由常规导电聚合物构成的复合热电材料及pn结叠层型热电转换装置。其p-型导电层由P3HT与PVDF混合构成，n-型导电层由PANI及PVDF混合构成，p-型和n-型导电层之间由PVDF聚合物绝缘层进行隔离。该种pn结叠层型热电转换装置由喷涂法制备，制备工艺简单、成本低廉。
