Thermoelectric Power of Carbon Fiber Reinforced Cement Composites Enhanced by Ca3Co4O9

摘要：

　　Micro-sized Ca3Co4O9 powder was prepared by solid phase method at 850-950℃ in air atmosphere.Seebeck effect of carbon fiber reinforced cement composites was enhanced efficiently by combining the Ca3Co4O9 powder of 3.0wt.% by mass of cement.The absolute thermoelectric power achieves 1.65 fold increase and is up to 58.6μV/℃ at room temperature.The lower activation energy of holes carriers and higher carrier concentration by doping Ca3Co4O9, are probably attributed to the increase of absolute thermoelectric power.
