导电炭黑/聚苯胺复合热电材料的制备及性能研究

摘要：导电聚合物由于其较低的热导率和较高的电导率理论上具备了作为热电材料的潜力，同时由于其热导率低、资源丰富、价格低廉等优点而备受关注。聚苯胺是目前研究较多的导电聚合物之一，聚苯胺基复合材料的热电性能也有了较大的提高。本文采用FeCl3 作为氧化剂与掺杂剂，通过原位聚合法制备了导电炭黑/聚苯胺的复合热电材料，并运用扫描电镜、拉曼光谱、X射线光电子能谱、透射电镜等对导电炭黑/聚苯胺复合材料的组成和微观结构进行了研究。同时通过测试复合材料的电导率，主要研究了导电炭黑含量对导电炭黑/聚苯胺复合材料电导率的影响，并与机械混合法所制备的导电炭黑/聚苯胺复合材料的性能进行了对比。81024

Preparation of thermoelectric properties of conductive carbon black/polyaniline composite materials

Abstract: Conductive polymer has a great potential to be used as a thermoelectric material due to its low thermal conductivity, low prices, and abundant resources。 Polyaniline (PANI) is one of the most studied conductive polymers, and the thermoelectric properties of PANI based composite materials have been greatly enhanced。 Herein, conductive carbon black (CB)/PANI thermoelectric composite materials were prepared via an in-situ polymerization method using FeCl3 as oxidant and dopant。 The composition and morphology of the CB/ PANI thermoelectric composite materials were investigated by scanning electron microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy。 The influence of CB content on the electrical conductivity of CB/ PANI composites was investigated。 The results were also compared with that of the CB/ PANI composites prepared by a mechanical mixing method。
