Herein, we design a two-step spray process to fabricate a thermal insulating superhydrophobic composite coating using epoxy resin mixed with hollow glass microsphere as primer coating and fluorine-modified SiO2 nanocoating as a waterproof layer. The composite coating shows durable superhydrophobicity and low thermal conductivity [0.051 W/(m·k)], which is endowed with excellent thermal insulating properties under light and heat, contact heat conduction (− 20 to 70 °C), and boiling water scouring environment. These multiple key properties that have been integrated into our composite film are expected to provide unique advantages for applications in building thermal management.
