Abstract
A fluorocarbon/palladium/magnesium-scandium hydrogen-chromic film and a preparation method thereof are provided. The film includes a magnesium-scandium composite film layer, a palladium catalytic layer, and a fluorocarbon film layer that are sequentially arranged on a substrate. The preparation method includes: growing the magnesium-scandium composite film layer on the substrate first, then growing the palladium catalytic layer in situ on the magnesium-scandium layer, and finally depositing the fluorocarbon film layer on Pd. According to the present invention, the catalytic effect of palladium is utilized to promote reversible conversion between hydrogen and hydrogen atoms during hydrogen absorption and dehydrogenation stages, and a composite scandium element is added to accelerate diffusion of the hydrogen atoms in a magnesium matrix and accelerate formation and decomposition of a hydride, such that the film can be repeatedly and rapidly switched between a reflective state and a transparent state.
