Abstract

Magnesium silicide (MgSi)/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 MgSi which was an approximately 60-nm-thick single crystal. The synthesized MgSi-coated CNTs exhibited n-type thermoelectric behavior confirming that n-type thermoelectric composite nanofibers were successfully obtained.

摘要

通过溶胶 - 凝胶法、镁热还原法和液 - 固相反应的联合工艺，成功合成了用作柔性热电材料的硅化镁（MgSi）/碳纳米管（CNT）热电纳米纤维。在所得产物中，每个碳纳米管都涂覆有厚度约为60纳米的单晶MgSi。合成的MgSi包覆碳纳米管表现出n型热电行为，证实成功获得了n型热电复合纳米纤维。
