THIN FILM SHEET AND PREPARATION METHOD THEREOF

The present disclosure provides a thin film sheet and a preparation method thereof. This thin film sheet is used for cleaning a slit-type spray nozzle, and comprises a substrate and a gel layer located on at least one side surface of the substrate, wherein the gel layer is produced from a swelling-type polymeric material. In the process of cleaning a spray nozzle of a coater, the presence of the gel layer allows the contact area between this cleaning sheet and the spray nozzle to be increased; and furthermore, the cleaning effect for the spray nozzle of the coater has been also greatly improved, since microporous structures of the surface of the gel layer can better adsorb dust on the spray nozzle of the coater. Meanwhile, the micro-elasticity of the gel layer can reduce scratches of the spray nozzle caused during cleaning. The thin film sheet of this disclosure improves cleaning effect and reduces the number of used thin film sheets required for cleaning, so as to save the cost, reduce the takt time of cleaning, and increase the production efficiency.
