Method for immobilizing photocatalyst on polyimide film and photocatalyst substrate fabricated by the same

摘要

The present invention relates to a photocatalyst immobilization method using a heat transfer printing method capable of minimizing peeling of titanium dioxide particles by immobilizing titanium dioxide particles on a polymer substrate by using thermal transfer printing, A method of immobilizing a photocatalyst using the heat transfer printing method according to the present invention includes the steps of preparing a heat transfer template having a photocatalytic coating layer on one surface thereof; Adhering a heat transfer template on both surfaces of the polymer substrate; And a heat transfer printing step of applying heat to the heat transfer template on both sides of the polymer substrate, wherein the photocatalytic coating layer of the heat transfer template is applied to the surface of the polymer substrate And the photocatalyst is immobilized on both surfaces of the polymer substrate.
