The invention discloses a photothermal conversion latex sponge and a preparation method and application thereof. The preparation method comprises the following steps: preparing a photothermal conversion filler into a water dispersion; adding the photothermal conversion filler water dispersion into the latex and mixing to prepare a porosity The latex sponge is obtained by immersing the latex sponge in a hydrogel solution, so that the hydrogel solution undergoes a cross-linking reaction in the pores to form a gel, and the photothermal conversion latex sponge can be obtained. The photothermal conversion latex sponge is prepared by the method, and can be applied to the field of sewage treatment, the field of seawater desalination, the field of photothermal power generation and the field of photothermal energy storage. The light-to-heat conversion latex sponge provided by the invention has high water evaporation capacity, wide absorption range, excellent thermal insulation performance, smooth water transport channel and high hydrophilicity. |
