Superhydrophobic film with Surface Pattern Structure for Low Adhesion and Method for Manufacturing the same

摘要

The present invention relates to a super water-repellent film having a surface pattern structure for low adhesion to control the shape and arrangement of micro / nano microstructures in the super water-repellent film to maximize the contact angle and cloudiness of the droplets and a method of manufacturing the same. The difference of the Gibbs free energy at the time of droplet movement computed using the Gibbs free energy equation on the surface of the base film; Patterns in micro / nano spaced apart from each other in the direction perpendicular to the cloud direction of the droplet, so that the patterns in micro / nano are in the liquid-solid surface contact area of the droplet. (Cassie-baxter) state, and the change of the area of the interface in the whole pattern ( ) Does not move in a non-zero direction, and the difference in the Gibbs free energy ( The pattern is arranged in micro units by arranging the droplets to move in a direction that does not occur.
