Abstract
A method of forming a thermal insulation porous film includes mixing 100 parts by weight of polysilsesquioxane-containing polymer, 20 to 75 parts by weight of surfactant, and 20 to 2000 parts by weight of solvent to form a thermal insulation coating material, wherein the polysilsesquioxane-containing polymer in the thermal insulation coating material is tube-shaped or sheet-shaped. The thermal insulation coating material is coated on a substrate, and then dried and sintered to form a thermal insulation porous film.
