采用溶胶-凝胶法、镁热还原法和液-固相反应相结合的方法，成功制备了硅化镁（Mg 2Si）/碳纳米管（CNT）热电纳米纤维柔性热电材料。在所得到的产物中，每个CNT被Mg 2Si涂覆，所述Mg 2Si是约60 nm厚的单晶。合成的Mg 2Si包覆碳纳米管表现出n型热电行为，证实了n型热电复合纳米纤维的成功获得。
Magnesium silicide (Mg2Si)/carbon nanotube (CNT) thermoelectric nanofibers for use as a flexible thermoelectric material were successfully synthesized through the combined processes of the sol-gel method, magnesiothermic reduction, and liquid-solid phase reaction. In the resulting product, each CNT was coated with Mg2Si which was an approximately 60-nm-thick single crystal. The synthesized Mg2Si-coated CNTs exhibited n-type thermoelectric behavior confirming that n-type thermoelectric composite nanofibers were successfully obtained.
