在多壁碳纳米管（MWCNT）分散的氯仿溶液中，通过氧化聚合法制备了多壁碳纳米管/聚3-己基噻吩（MWCNT/P3 HT）复合材料。采用X射线衍射（XRD）和傅里叶变换红外光谱（FTIR）分析了复合材料的物相组成。在293 - 423 K温度下测量了冷压成丸后复合粉末的热电性能。含30wt%多壁碳纳米管的样品的电导率显示出在此温度范围内从0.13 S/cm到0.11 S/cm的电导率逐渐降低，并且伴随着塞贝克系数从9.7 μ V/K增加到11.3 μ V/K。(C)2011爱思唯尔有限公司版权所有。
Multiwalled carbon nanotube/poly(3-hexylthiophene) (MWCNT/P3HT) composites were prepared by oxidative polymerization of 3-hexylthiophene in a MWCNTs dispersed chloroform solution. The phase composition of the composite materials was analyzed by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The thermoelectric properties of the composite powders, after cold pressing into pellets, were measured at temperatures between 293 and 423 K. The electrical conductivity of samples containing 30 wt% MWCNT displayed a gradual decrease in conductivity from 0.13 to 0.11 S/cm across this temperature range and was accompanied by an increased in the Seebeck coefficient from 9.7 to 11.3 mu V/K.
