| 摘 要： | 本文首先通过溶液混合法将碳纳米管(CNTs)分散到聚碳酸酯(PC)基体中,然后将获得的PC/CNT絮状物通过高温模压的方法制备了一种柔性的高热电性能PC/CNT复合材料。PC/CNT复合材料断面形貌分析表明,CNTs均匀地分散在PC基体中。此外,PC/CNT复合材料的导电性随着CNTs含量的增加而急剧增加,而Seebeck系数几乎保持恒定,使得材料的功率因子随着CNTs含量的增加而快速增加,最大功率因子达到4.6μW·m-1·K-2。

| Abstract: | Carbon nanotubes(CNTs) were dispersed in polycarbonate(PC) matrix by solution method. Then the obtained PC/CNT flocculation was used to prepare the flexible thermoelectric PC/CNT composites by compression molding. The fractured morphology of PC/CNT composite suggested that CNTs are distributed homogenously in the PC matrix. Besides, with increasing CNT contents, the electrical conductivities increase dramatically whereas the Seebeck coefficients nearly remain constant. This leads to the rapid increasing trend of power factor with CNT content for the PC/CNT composites. The maximum power factor is 4.6 μW·m^-1·K^-2. |
