Self‐healing hydrophobic light‐to‐heat conversion membranes for interfacial solar heating are fabricated by deposition of light‐to‐heat conversion material of polypyrrole onto a porous stainless‐steel mesh, followed by hydrophobic fluoroalkylsilane modification. The mesh‐based membranes spontaneously stay at the water–air interface, collect and convert solar light into heat, and locally heat only the water surface for enhanced evaporation.
