AgNWs and Yb filled skutterudites Yb0.3Co4Sb12 were prepared by polyol reduction of silver nitrate and melting quenching annealing method. The nanocomposite AgNWs/Yb0.3Co4Sb12 were obtained by combining ultrasound technology and spark plasma sintering with different AgNWs weight ratio. The microstructure of the samples were studied by XRD and FE-SEM images confirmed that AgNWs were well dispersed in Yb0.3Co4Sb12 matrix. The thermoelectric properties of the samples with different AgNWs contents were investigated in detail. The results show that well-dispersed AgNWs in the bulk Yb0.3Co4Sb12 can give rise to a much higher electrical conductivity and thermal conductivity without a noticeable decrease in Seebeck coefficient, which suggests the improvement of composites with AgNWs thermoelectrical was limited. The maximum ZT about 1.02 is observed with AgNWs contents of 0.5wt%.
