Abstract
A process for fabricating a thermochromic film is disclosed which includes the steps of dispersing a predetermined amount of vanadium dioxide (VO2) nanoparticles in a predetermined amount of poly(methyl methacrylate) (PMMA), stirring a mixture thereof for a first predetermined amount of time, generating cross-links to molecule chains of the PMMA in the mixture, and blade coating a predetermined thickness of the cross-linked mixture on a substrate to form the thermochromic film.
