Abstract Superhydrophobic coatings with a thermal insulation property were fabricated via rapid process. In brief, coating solutions containing low‐melting‐point glass powder, antimony‐doped tin oxide nanopowder, and other additives first applied to substrates. Subsequently, the coated samples underwent process in tube furnace at 690°C for 2 min. The relationship between nanopowder content coatings’ performance was examined systematically. hydrophobic properties measured their morphology, phase, surface roughness characterized. optimized has water contact angle of 154°, demonstrating its superhydrophobicity. infrared transmittance optimal sample 780 2500 nm is reduced by 13.3%, after being exposed an lamp 5 min, temperature below 4.7°C lower, compared bare substrate, showing dual functionalities prepared samples. Moreover, since can be achieved conventional tempering process, fabrication this simple readily realized.
