摘要
热电材料能够实现热能与电能之间的相互转化,实现热能再利用。无机热电材料具有优异的热电性能,但由于其加工性较差及柔性差,限制了其在柔性材料领域的发展。聚3,4-乙烯二氧噻吩(PEDOT)具有优良的热电性能及良好的柔性,通过与合适的无机材料复合能够有效提高其热电性能。文中综述了近年来国内外PEDOT基热电材料的研究进展,详细介绍了碳纳米材料、Bi-Te合金、二维层状材料、金属纳米粒子及多元材料改性PEDOT复合材料的制备工艺与热电性能,最后总结了提高PEDOT基复合材料热电性能的方法。
Thermoelectric materials can realize the mutual conversion between thermal energy and electrical energy and realize the reuse of thermal energy.Inorganic thermoelectric materials have excellent thermoelectric properties,but their poor processability and poor flexibility limit their development in the field of flexible materials.Poly(3,4-ethylenedioxythiophene)(PEDOT)has excellent thermoelectric properties and good flexibility,and its thermoelectric properties can be effectively improved by compounding with suitable inorganic materials.The research progress of PEDOT-based thermoelectric materials in recent years was reviewed.The preparation technology and thermoelectric properties of PEDOT modified with carbon nanomaterials,Bi-Te alloy,two-dimensional layered materials,nano-metals were introduced in detail.Finally,the methods to improve the thermoelectric properties of PEDOT composites were summarized.
