A new self-desalting solar evaporation system based on a vertically oriented porous polyacrylonitrile foam

Abstract: A new self-desalting evaporation system comprising reduced graphene oxide/cotton fabric and a vertically oriented porous polyacrylonitrile film exhibited excellent self-desalting performance and high photothermal performance.

“…[11][12][13][14] To this end, immense efforts have been dedicated to developing an advanced absorber to achieve the above properties. [13][14][15][16][17][18][19][20][21][22][23][24][25][26] So far, multitudinous materials including plasmonic metals, 13,[15][16][17][18] carbon-based nanostructures, 14,[19][20][21][27][28][29] semiconductors 22,23 and bio-inspired materials [24][25][26][30][31][32] have been investigated by researchers to boost the efficiency of solar energy harvesting further. For instance, Zhu's group 18 demonstrated a gold based plasmonic absorber, which has over 90% efficiency under 4 sun (4 kW m À2 ) illumination.…”

“…A long-term challenge is to evaluate the performance of solar evaporation devices correctly and uniformly. The current research has a programmatic calculation formula, but it lacks standardised measurement techniques and evaporation calculation efficiency [62]. Therefore, it is unscientific to directly compare the results of different jobs, as even the same material will demonstrate significant differences in evaporation efficiency during different seasons and at different times of the day.…”

“…Materials with excellent photothermal conversion capabilities including metal nanoparticles, 7,9,10 metal oxides, 11‐13 carbon‐based materials, 14‐18 polymer materials, 19‐21 and semiconductor materials 22‐24 have been used for solar water evaporation. Typically, photothermal conversion materials are deposited or coated on porous materials such as a filter paper, 25‐28 fabrics, 29‐34 or a polymer film 35‐40 to achieve large‐area light absorption. These materials are generally large in area, flexible, and foldable, but they cannot float in water due to their hydrophilic nature, and a supporting layer of robust and hydrophobic foam such as poamedpolystyrene is usually required to construct floatable solar evaporation devices from them.…”
