文摘
- •
Selective absorber films, with unique foamed nanostructure, are firstly obtained by hydrothermal method on stainless steel, without using any porogen.
- •
The films, which comprise large numbers of nanoparticle agglomerates and nanopores, display a solar absorbance of 0.92 and a thermal emittance of 0.12.
- •
The films prove benign thermal stability and performance at 450 °C, without crackings within entire structure.
- •
The strategy is especially simple, pollution-free, low-cost and novel.
