| 摘 要： | 将纳米氧化镍作为热电组份掺入水泥浆中以提高水泥基材料热电性能,研究了纳米氧化镍对水泥基材料热电性能的影响,并分析其作用机理。结果表明,随着纳米氧化镍掺量的增加,水泥基复合材料的Seebeck系数及电导率逐渐增大,当纳米氧化镍掺量为水泥质量的5.0%时,水泥基复合材料的Seebeck系数最大,约为4050μV/℃,远高于碳纤维增强水泥基材料,电导率此时也达到最大,约为6.76×10-5 S/cm,远高于硬化水泥浆试样。

| Abstract: | Nano-nickel oxide was incorporated into cement paste as the thermoelectric component to increase the thermoelectric performance of cement paste. The thermoelectric performance and mechanism of these cement composites were researched in this paper. Results showed that the Seebeck coefficient and conductivity of the cement composite increased with the content of NiO powders. When the NiO content was 5.0%,the maximum Seebeck coefficient of cement composite was tested 4050 μV/℃,which was far higher than that of carbon fiber reinforced cement composite. The maximum electrical conductivity was about 6.76×10^-5 S/cm when the NiO content was 5.0%,which was far higher than that of hardened cement paste. |
