Abstract

The invention discloses a preparation device of a structure type infiltration gradient surface. The preparation device comprises an electroplating power supply, an electroplating bath, an anode plate and a cathode plate; the electroplating bath contains an electroplating solution; the anode plate and the cathode plate are soaked into the electroplating solution; the anode plate is connected with an anode of the electroplating power supply; the cathode plate is connected with a cathode of the electroplating power supply; the anode plate and the cathode plate are arranged at a set inclination angle; and the distance between the anode plate and the cathode plate changes in a continuous gradient manner in the arrangement direction of the anode plate and the cathode plate. According to the preparation device, the anode plate and the cathode plate are fixed in the electroplating solution at the set angle, and electroplating electric current continuously changes in the electrode arrangement direction, so that the structure type infiltration gradient surface of which the metal grain sizes and density change in a gradient manner is formed on the cathode plate; the structure type infiltration gradient surface is simple in preparation process, simple in structure, and is easy to realize; and by controlling electroplating parameters, the distance and the arrangement angle between the anode plate and the cathode plate, chemical components of the anode plate, and the like, various infiltration gradient surfaces meeting the practical industrial requirements can be prepared.

Description

technical field [0001] The invention relates to the technical field of material preparation, in particular to a preparation device for a structured wetting gradient surface. Background technique [0002] Wetting gradient surface refers to a special gradient surface whose surface wettability changes continuously with the change of surface position. Due to the special wetting properties, the gradient surface can realize the directional delivery of liquids, which plays an important role in pharmaceuticals, smart microfluidic devices, etc.; at the same time, this directional delivery of liquids is not affected by gravity conditions, so it can be used in aerospace and Submarine engineering; with the directional movement of liquid droplets, steam condensation can form stable droplet condensation, which greatly enhances condensation heat transfer; in addition, the infiltration gradient can realize efficient adsorption and separation of proteins and cells. Therefore, in recent year...
