Abstract

The invention discloses an electroplating method based simple super-hydrophobic tube inner surface preparation device. The electroplating method based simple super-hydrophobic tube inner surface preparation device comprises a tube fitting and an electroplating anode which are coaxially arranged between a base and a top plate, wherein a lead screw passes through the top plate and the base for enclosing the electroplating anode and the tube fitting into a sealed reaction cavity; a conductive copper sheet is mounted on the upper surface, at the top end of the tube fitting, of the electroplating anode; the upper side surface of the conductive copper sheet is connected to a guide wire; the guide wire is accessed into a power supply through a top plate through hole; the top plate and the tube fitting are provided with openings, and are accessed into a circulating pipeline; a peristaltic pump drives a solution in a plating solution slot to enter the tube fitting to react, and then flow back into the plating solution slot to accomplish a cycle; and an ultrasonic transducer is mounted at the lower end of the base, and is coaxial with the tube fitting. The electroplating method based simplesuper-hydrophobic tube inner surface preparation device solves the problem that in-tube super-hydrophobic surface preparation is difficult, has the advantages of being high in cost performance, conveniently and quickly replacing the tube fitting, being strong in sealing property, adopting ultrasonic cavitation effect to reduce retention of gas bubbles in an electroplating process, and acceleratessurface reaction, so that uniformity of a hydrophobic surface structure is improved, and the purpose of controlling surface topography can be achieved by programing specified current output.

Description

technical field [0001] The invention belongs to the technical field of material surface modification, in particular to a simple super-hydrophobic tube inner surface preparation device based on an electroplating method. Background technique [0002] Surface wettability is an important property of the surface of solid materials. Changing the wettability of the solid surface to hydrophilic or hydrophobic can effectively improve some shortcomings of the material and expand the application range of the material. The solid surface with superhydrophobic properties is almost in a non-wetting state after contact with water droplets, and this state plays an important role in anti-freezing, microfluidics, pipeline drag reduction, anti-corrosion and self-cleaning. After further research, it was found that , the micro-nano rough structure on the surface is the main reason for achieving superhydrophobic properties. [0003] Although there are many methods for preparing superhydrophobic s...
