AI Technical Summary
Existing photothermal conversion devices suffer from severe heat loss, resulting in an imbalance between light and heat energy conversion. This limits the efficiency and widespread application of solar water evaporation technology. In addition, traditional loading methods result in uneven loading on fractal metal substrates, which cannot penetrate deeply and affect photothermal conversion efficiency.
Photothermal composite materials were prepared on fractal metal substrates using electrophoretic micro-nano assembly technology. Polyaniline was uniformly and effectively loaded onto the surface of nickel dendrites through electrophoretic reaction to form polymer fractal metal composite materials, which were then woven into photothermal devices. The loading parameters were controlled using electrophoretic micro-nano assembly technology to improve photothermal conversion efficiency.
This invention achieves highly efficient photothermal conversion, significantly improves water evaporation efficiency, reduces heat loss, and is simple and inexpensive to prepare, making it suitable for large-scale production.
