    Abstract: The present invention relates to a method of manufacturing a micropattern surface with a reentrant structure with hydrophobicity and oleophobicity through a simple process using capillary force. The method of the present invention includes a step of forming a resin layer by applying an ultraviolet rays (UV) curable resin on a first substrate; a step of forming a pillar-shaped fine pattern on a second substrate; a step of bringing the resin layer and the fine pattern into contact with each other by moving the first substrate or the second substrate so that the resin layer and the fine pattern face each other; and a step of curing the resin by radiating ultraviolet rays while the resin located around a pillar of the fine pattern moves a certain distance along the pillar in the longitudinal direction of the pillar of the fine pattern by capillary force.

    Abstract: The present invention discloses a process and device for preparing laser PVC. The device includes an upper transmission roller, a support mechanism, a spraying mechanism, an impurity removal mechanism, and a lower transmission roller; the upper transmission roller is disposed above the lower transmission roller, and the two are configured to implement delivery of a PVC film at a station for preparing a laser layer by spraying; the support mechanism is disposed between the upper transmission roller and the lower transmission roller and is in contact with a back surface of the PVC film, and the spraying mechanism is disposed opposite to the support mechanism; and a curing mechanism is disposed in a fitting manner at the coating position; and the impurity removal mechanism is disposed at a front end of the spraying mechanism.
