摘　　要：淡水资源紧缺是一个亟待解决的全球性难题。以聚丙烯酰胺水凝胶为输水体,以炭黑为光热转化材料,设计了炭黑/聚丙烯酰胺复合水凝胶蒸发器。结果表明,该蒸发器在一个太阳光照强度下的蒸发率达2.06 kg·m^(-2)·h^(-1)。碳纳米管/聚丙烯酰胺复合水凝胶蒸发器的蒸发率达2.66 kg·m^(-2)·h^(-1),但从原料成本考虑,碳纳米管80万元/t,而炭黑仅为0.99万元/t。炭黑蒸发器具有显著的经济优势。Scarcity of freshwater resources is a global problem that needs to be solved urgently.In this paper,a carbon black/polyacrylamide composite hydrogel evaporator was designed using polyacrylamide hydrogel as a water transport body and carbon black as a photothermal conversion material.The results show that the evaporation rate of this evaporator reaches 2.06 kg·m^(-2)·h^(-1) at one solar light intensity,while that of the carbon nanotube/polyacrylamide composite hydrogel evaporator reaches 2.66 kg·m^(-2)·h^(-1).Considering the cost of raw materials,carbon nanotubes are 800,000 yuan/tonne and carbon black is only 0.99 million yuan/tonne,and the carbon black evaporator has a significant economic advantage.
