The invention discloses a transparent
zinc mesh, a preparation method and application thereof and an electrochromic device, and belongs to the technical field of
electrochromism and
photochromism. The transparent
zinc mesh comprises a
metal mesh and elemental
zinc electrically deposited on the surface of the
metal mesh. An electrodeposition solution adopted by the electrodeposition contains zinc ions, polyethyleneimine and
boric acid. According to the invention, polyethyleneimine and
boric acid are added into an electro-deposition solution, and the polyethyleneimine and
boric acid cooperate to regulate and control the
deposition process of a zinc simple substance on a
metal mesh, so that the transparent zinc mesh with a smooth and flat surface is obtained. The
high transmittance of visible light is 75%, and the
cycling stability is good. As the surface is smooth and flat, and the specific surface area is large, a uniform
electric field can be provided, continuous accumulation of zinc at a high
electric field intensity position is avoided, more effective
nucleation sites are provided, uniform zinc deposition can be realized, and growth of zinc dendrites can be inhibited.
