测量有机热电材料的面内热导率是具有挑战性的，但也是至关重要的。在这里，深入探索了一种基于温度波分析的研究自支撑薄膜面内导热系数的方法(通过使用商业设备)。这种主题法需要厚度大于10微米、面积大于1厘米(2)的独立薄膜，这对于大多数可溶液处理的有机热电材料来说并不难获得。我们评估了不同类型的样品的热导率和各向异性比，包括绝缘聚合物、未掺杂的半导体聚合物、掺杂的导电聚合物和一维碳纤维厚纸。这种方法有助于快速筛选各种有机热电材料的面内导热系数。(C)2016年作者(S)。除另有说明外，所有文章内容均受知识共享署名(CC BY)许可证(http://creativecommons.org/licenses/by/4.0/).的许可
Measuring the in-plane thermal conductivity of organic thermoelectric materials is challenging but is critically important. Here, a method to study the in-plane thermal conductivity of free-standing films (via the use of commercial equipment) based on temperature wave analysis is explored in depth. This subject method required a freestanding thin film with a thickness larger than 10 mu m and an area larger than 1 cm(2), which are not difficult to obtain for most solution-processable organic thermoelectric materials. We evaluated thermal conductivities and anisotropic ratios for various types of samples including insulating polymers, undoped semiconducting polymers, doped conducting polymers, and one-dimensional carbon fiber bulky papers. This approach facilitated a rapid screening of in-plane thermal conductivities for various organic thermoelectric materials. (C) 2016 Author(s).
