摘要
Utilizing solar energy to evaporate water is an environment-friendly and promising approach for various applications such as seawater desalination. Various photothermal materials can be developed for evaporating water, however, there are still some drawbacks such as complicated synthesis processes, weak/narrow absorbance, bulkiness, and low evaporation rate, which severely limit their commercial applications. Herein, we reported the preparation of electrochemically-etched carbon fiber cloth with surface-coated carbonized polyaniline nanowires (ECFC/CPANW) based on thermally-treated pre-oxidized polyacrylonitrile fiber cloth for highly efficient solar steam generation. This ECFC/CPANW composite has the advantages of low thermal conductivity, effective broadband solar absorption, good hydrophilicity and water transfer ability. When ECFC/CPANW and polyurethane foam are bound together as a solar evaporator, ECFC/CPANW achieved the highest vaporization efficiency of up to 93.7% under 1 sun illumination, which is more efficient than those of most materials previously reported. Therefore, this kind of photo-thermal conversion material with low cost, good stability and environmental friendliness could envision promising practical application for water treatment.
