Surface microstructural array with self-transportation performance and forming method thereof

Abstract

The invention discloses a surface microstructural array with self-transportation performance and a forming method thereof. A single microstructure of the surface microstructural array is a shark scaleimitating structure, the shark scale imitating structures are triangular protrusions and are made from photosensitive resin, and the size is in micron order. Nano particles are distributed on the surfaces of the microstructures, and micro/nano composite structures are formed by the nano particles and the shark scale imitating structures. Multiple composite structures are evenly distributed on thetarget face of a formed part, and the surface microstructural array is formed. According to the forming method of the microstructural array, the surface microstructural array is prepared through an electromagnetically assisted vibrating face projection micro-stereoscopic photoetching system according to certain steps. According to the surface microstructural array, automatic transportation of condensate liquid drops can be achieved, and the condensation efficiency is improved. According to the forming method, by means of high-frequency vibration of an electromagnetic assisted vibration device, nano particle aggregations can be reduced, even distribution of the nano particles is achieved, and the forming precision and the forming quality are improved. A forming system moving platform can do horizontal rectilinear motion in the Y-axis direction and the X-axis direction, the area of a forming layer face and the size of the formed part are expanded, the forming time is shortened, and theforming efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of surface modification and 3D printing molding, and in particular relates to a microstructure array on the inner wall of a biological culture dish with antibacterial properties and a molding method thereof. Background technique [0002] In recent years, with the continuous improvement of energy-saving emission reduction and sustainable development requirements in the industrial production process, the importance of condensate collection and recycling in the fields of chemical industry, metallurgy, machinery and other fields has become increasingly prominent. According to the different surface wettability, the condensation process is mainly divided into film condensation and drop condensation, in which the heat transfer rate of the latter is several times or even ten times that of the former. Literature research shows that constructing functional surfaces with superhydrophobic properties on the surface of pi...
