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.

耐用的整体式聚合物泡沫，可高效产生太阳能蒸汽

高效且经济高效的太阳能蒸汽产生需要自浮式蒸发器，该蒸发器可以将光转换为热量，防止不必要的热损失，并且在没有太阳能集热器的情况下大大加速了蒸发。当前，最有效的蒸发器（在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式薄板。在这里，我们介绍了一种新的聚合物，可以轻松地将其溶液加工成自浮式整体泡沫。单组分泡沫可用作蒸发器，在1个太阳下的效率可与最佳石墨烯基蒸发器相媲美。即使在0.5阳光下，效率也可以达到80％。此外，该泡沫具有机械强度，对300°C的热稳定性以及对有机溶剂的化学耐受性。
