摘　　要：介绍了材料Seebeck效应的定义及其原理,并对比分析了水泥基材料单掺和复掺不同热电相材料(碳材料、金属氧化物、金属和部分工业废弃物)的热电性能,发现在温差作用下产生多重热电载流子的迁移和扩散作用。复掺热电相的水泥基复合材料不仅具有更高的Seebeck系数,而且其热电性能更加稳定,这对基于水泥基复合材料温差发电效应的交通结构融雪化冰、海洋混凝土结构腐蚀阴极防护等具有重要工程意义。Firstly,the definition of material Seebeck effect and its principle were introduced,then the thermoelectric properties of cement-based material with different thermoelectric phase materials(carbon material,metal oxide,metal and some industrial waste)were investigated,which found that the migration and diffusion of multiple thermoelectric carriers were generated under the effect of temperature difference.Cement-based composites mixed with compounded thermoelectric phases not only have higher Seebeck coefficient,but also have more stable thermoelectric properties.It is of great engineering significance to melt ice of traffic structure and cathodic protection against corrosion of marine concrete structures based on the temperature difference power generation effect of cement-based composites.
