Abstract

The aim of this work is the fabrication of electrically insulating composite rigid polyurethane foams with improved thermal conductivity. Therefore, this study is focused on the effect of aluminum nitride (AlN) on the thermal and electrical conductivities of rigid polyurethane foams. For this purpose, aluminum nitride/rigid polyurethane composite foams were prepared using a three-step procedure. The electrical and thermal conductivities of the foams were characterized. The thermal transitions, mechanical properties and morphology of the foams were also examined. The results reveal that AlN induces an increase of the thermal conductivity of rigid polyurethane foam of 24% which seems to be a relatively noticeable increase in polymeric foams. The low electrical conductivity of the foams is preserved.

氮化铝填料对硬质聚氨酯泡沫塑料导热性能的改善

本工作的目的是制备具有改进导热性的电绝缘复合硬质聚氨酯泡沫。因此，本研究的重点是氮化铝（AlN）对硬质聚氨酯泡沫热导率和电导率的影响。为此，使用三步程序制备氮化铝/硬质聚氨酯复合泡沫。对泡沫的电导率和热导率进行了表征。还考察了泡沫的热转变、力学性能和形态。结果表明，AlN使硬质聚氨酯泡沫的热导率增加了24%，这似乎是聚合物泡沫中相对显著的增加。泡沫的低电导率得以保留。
