Abstract

The invention discloses a super-hydrophobic self-cleaning resin lens and a manufacturing method thereof. The surface of the lens is provided with micron-grade porous structures which are distributed in order. Each porous structure is composed of multiple holes, the aperture of each hole is 8-13 microns, the distance between adjacent holes is 14-20 microns, and the depth of each hole is 40-45 microns. Glycerin monostearate is granular and evenly distributed on the surfaces of the porous structures to form a nano structure. According to the method, laser micromachining and modification are carried out on the surface of the lens so as to obtain a dual-micro structure, so that the lens has hydrophobic property, mist is prevented from forming, dirt cannot be attached to the surface of the lens easily, the self-cleaning function is achieved to a certain degree, optical performance of the lens is not changed, and the service life of the lens is prolonged.

Description

technical field [0001] The invention relates to an optical lens manufactured by laser microprocessing, in particular to a method for manufacturing a superhydrophobic self-cleaning resin lens. Background technique [0002] Superhydrophobic surface has the characteristics of waterproof, anti-fouling, and can reduce the viscosity of fluid, and it is one of the hotspots in the research of functional materials. For a hydrophobic solid surface, when there are tiny protrusions on the surface, some air will be "closed" between the water and the solid surface, causing most of the water droplets to be in contact with the air, and the direct contact area with the solid is larger. decrease. Due to the surface tension of water, the shape of water droplets on this rough surface is close to spherical, and its contact angle can reach more than 150 degrees, and water droplets can roll freely on the surface. Even if there are some dirty things on the surface, they will be taken away by the ...
