摘　　要：采用发泡法制备了聚偏二氟乙烯(PVDF)泡沫,并在其上沉积了光热转换材料聚吡咯(PPy),制备了PVDF/PPy复合多孔泡沫光热材料。PVDF/PPy泡沫内的多孔结构有利于水分的输运,并且黑色的PPy有效地增加了其光吸收性能和光热转换性能。在PVDF/PPy-3中,其表面温度为56.3℃,光热蒸发速率为1.5612 kg/(m^(2)·h)。并且具有较好的稳定性和环境耐久性,可以在不同环境下长时间使用,具有较好的实用性。PVDF/PPy composite porous foam thermal materials were prepared by foaming method and photothermal conversion material polypyrrole was deposited on the foam.The porous structure in PVDF/PPy foam is conducive to water transport,and the black PPy effectively increases its light absorption performance and photothermal conversion performance.In PVDF/PPy-3,the surface temperature is 56.3℃,and the photothermal evaporation rate is1.5612 kg/(m^(2)·h).Moreover,it has good stability and environmental durability.It can be used in different environments for a long time and has good practicability.
