چکیده انگلیسی
The Graphene/Mn0.7Zn0.3Fe2O4 composites were synthesized by coprecipitation and sintered by a spark-plasma-sintering (SPS) method. The thermoelectric properties of the sintered composites were evaluated in the temperature range of 343-973Â K. The effect of graphene on the thermoelectrical properties of Mn0.7Zn0.3Fe2O4 was investigated. The dispersion of 2Â wt% graphene in Mn0.7Zn0.3Fe2O4 effectively enhanced the electrical conductivity and the absolute value of Seebeck coefficient, while thermal conductivity was decreased. The results showed that the maximum ZT value of 0.035 at 973Â K was obtained in the composite with 2Â wt% graphene.
