Embodiment 1

[0145] (1) film

[0146] A film having a thickness of 100 μm was used, consisting of a polymer mainly composed of polypropylene (melting point: 144° C., glass transition temperature: −20° C.).

[0147] (2) Mold

[0148] The surface of the stainless steel plate is coated with a material mainly composed of Ni with a thickness of about 100 μm. Then, a micropore structure with a diameter of about 0.3 μm to 0.6 μm and a depth of about 7 μm to 10 μm is formed on the entire surface of the mold by laser processing to produce a mold. The area where micropores were formed accounted for 20% of the surface where micropores were formed.

Abstract

Provided is a highly liquid-repellent and highly durable resin structure, in which the liquid-repellency is not deteriorated even by external conditions. A resin structure according to the present invention has a liquid-repellency, and includes: a base layer; and a fiber layer comprising a multitude of fibers. The fiber layer includes: a substantially perpendicular section which is located close to the base layer and in which the fibers extend substantially perpendicular to the surface of the base layer; and a substantially parallel section which is located away from the base layer and in which the fibers extend substantially parallel to the surface of the base layer. All the fibers constituting the fiber layer are connected to the surface of the base layer, and extend from the surface ofthe base layer.

Description

technical field [0001] The present invention relates to a resin structure exhibiting a liquid-repellent effect by having a fiber layer composed of a plurality of fibers on the surface, and a method for producing the resin structure. Background technique [0002] Conventionally, as a method of expressing a liquid-repellent effect on the surface of a structure, a method of applying a resin having a low surface energy such as a fluoropolymer to the structure has been widely used. However, when only coating is performed, the liquid repellency is limited, and the expected liquid repellency cannot be obtained. Therefore, a method of obtaining liquid repellency at a level higher than that obtained by a coating method by adding a fine structure to the surface of a structure has been proposed (Patent Document 1). [0003] In addition, as a microstructure exhibiting a liquid-repellent effect, anisotropic protrusions directed in directions other than the direction perpendicular to the...
