摘要
In this study, Mn-Zn ferrites with three different multiwalled carbon nanotubes (MWNTs) concentration, 1,2,3 wt%, were used to compare the effect of MWNTs on thermoelectric properties of the composites. The dimensionless figure of merit (ZT) of the composites at the low contents (1 and 2 wt%) of MWNTs have shown significantly increased values compared to those of composites at the high contents (3 wt%) in the temperature range of 323-973 K. The maximum ZT of 0.038 was obtained at 2 wt%. It is considered that the improved thermoelectric performance of the composite mainly originated from electrical conductivity that is attributed to the increased carrier concentration or carrier mobility.
