Efficient and cost-effective solar steam generation requires self-floating evaporators which can convert light into heat, prevent unnecessary heat loss and greatly accelerate evaporation without solar concentrators. Currently, the most efficient evaporators (efficiency of ∼80% under 1 sun) are invariably built from inorganic materials, which are difficult to mold into monolithic sheets. Here, we present a new polymer which can be easily solution processed into a self-floating monolithic foam. The single-component foam can be used as an evaporator with an efficiency at 1 sun comparable to that of the best graphene-based evaporators. Even at 0.5 sun, the efficiency can reach 80%. Moreover, the foam is mechanically strong, thermally stable to 300 °C and chemically resistant to organic solvents.

用于高效太阳能蒸汽产生的耐用整体聚合物泡沫†

高效且经济高效的太阳能蒸汽发电需要自浮式蒸发器,该蒸发器可以将光转化为热能,防止不必要的热量损失,并在无需太阳能聚光器的情况下大大加速蒸发。目前,最高效的蒸发器(1个太阳下的效率约为80%)总是由无机材料制成,这些材料很难模制成整体片材。在这里,我们提出了一种新的聚合物,它可以很容易地通过溶液加工成自漂浮的整体泡沫。单组分泡沫可用作蒸发器,其在 1 太阳时的效率可与最好的石墨烯基蒸发器相媲美。即使在0.5太阳光下,效率也能达到80%。此外,该泡沫机械强度高,热稳定性高达 300 °C,并且耐有机溶剂化学腐蚀。
