Abstract
A method of manufacturing colorful thermal insulation films is provided. A substrate is connected with a metal adhesion layer and then the metal adhesion layer is connected with a porous anodic aluminum oxide (AAO) layer. A porosity of the AAO layer is changed by pore-widening. Thereby the thermal insulation film produced shows the color by the structure color of the AAO layer. Thus no dyes and organic compounds are required to be added during manufacturing process and environmental pollution caused by these substances can be avoided. The pore-widening changes the porosity of the AAO layer and further provides convenient color adjustment so that the colorful thermal insulation film with different colors can be produced easily. Besides providing attractive appearance, the colorful thermal insulation film filters out light with specific wavelengths.
