Abstract

The invention relates to a preparation method of foamy copper for detection of sucrose concentration. The preparation method includes pretreatment of a polyurethane foam material, chemical copper plating, electroplating and sintering reduction. Twice coarsening is carried out during pretreatment, and ultrasonic vibration is employed to assist deposition of copper during electroplating. The foamy copper prepared by the invention has improved corrosion resistance. The foamy copper preparation process has the characteristics of speediness, reusable raw materials, simple preparation process, simple equipment condition, low cost, and improved production efficiency. The prepared foamy copper has the advantages of high porosity, large specific surface area and light weight.

Description

technical field [0001] The invention relates to a preparation method of foamed copper, in particular to a preparation method of foamed copper for detecting sucrose concentration. [0002] Background technique [0003] Metal foam has a three-dimensional network structure, has the structural characteristics of high porosity, large specific surface area, light weight, certain strength and toughness, and strong energy absorption. It has been widely used in the fields of machinery, metallurgy, environmental protection, electronics, aviation, and chemical industry. a wide range of applications. With the development of the electroplating industry, higher requirements are put forward for electroless copper plating, the most important of which is to improve the stability of the plating solution and the copper deposition speed. Usually, the stability of the plating solution increases, and the copper deposition speed decreases; on the contrary, Increase the copper sinking speed, then...
