Method for locally preventing ice on super-hydrophobic transparent film

The invention provides a method for local anti-icing on a super-hydrophobic transparent film. The preparation method comprises the following steps: firstly, preparing a transparent PDMS film with a super-hydrophobic property by utilizing a simple template method, namely etching a #-shaped concave-convex surface on a brass sheet by utilizing an optical fiber laser marking machine to serve as a template, then uniformly smearing PDMS mixed liquid mixed with a curing agent on the surface of the processed template, heating and curing, and stripping the film from the template, so as to obtain the transparent PDMS film with the super-hydrophobic property. The transparent super-hydrophobic PDMS film is obtained. The obtained sample not only has the super-hydrophobic characteristic, but also retains excellent transparency, and pollution elements such as fluorine are not involved in the preparation process. And processing a round hole in the prepared film by using the optical fiber laser marking machine again. The PDMS
