Waxgels are known for their unique ability to generate sacrificial wax layers during anti-icing. To address the severe slow regrowth of the wax layer, here, carbon black is incorporated in the waxgel network to endow photothermal function. The rate of the regrowth of the wax layer is raised by >6 times under natural light conditions. Meanwhile, the photothermal waxgel showed improved anti-icing performances in terms of delayed ice formation and lower ice adhesion strength.
