Embodiment 1
[0028] The present invention builds superlubricating interface (such as figure 1 ), and produce recoverable depressions under the action of an external magnetic field to move and transport droplets. The small-radius and fast-speed circular motion through the depression realizes the mixing and stirring of the droplets and speeds up the reaction rate. Specific steps are as follows:
[0029] (1) Take 10 grams of silicone oligomer, 1 gram of crosslinking agent, and 6 grams of iron powder and stir and mix evenly;
[0030] (2) Take an appropriate amount of the obtained mixture and drop it on a custom-made mold of 12 square centimeters, let it stand for 30 minutes, pre-polymerize at 80 degrees Celsius for 30 minutes, then contact the 1 mm thick sponge substrate with it, and polymerize at 80 degrees Celsius for 8 hours, combine as figure 2 .
[0031] (3) The substrate is peeled off, and laser engraving is performed on the non-sponge surface to obtain a rough surface. Then 1.2 ml...
Embodiment 2
[0035] The present invention builds superlubricating interface (such as figure 1 ), and in
[0036] external magnetic field
[0037] Create recoverable depressions that move transported droplets. The small-radius and fast-speed circular motion through the depression realizes the mixing and stirring of the droplets and speeds up the reaction rate. Specific steps are as follows:
[0038] (1) Take 15 grams of silicone oligomer, 1.5 grams of crosslinking agent, and 9 grams of iron powder and stir and mix evenly;
[0039] (2) Take an appropriate amount of the obtained mixture and drop it on a custom-made mold of 12 square centimeters, let it stand for 30 minutes, pre-polymerize at 80 degrees Celsius for 30 minutes, then contact the 1 mm thick sponge substrate with it, and polymerize at 80 degrees Celsius for 8 hours, combine as figure 2 .
[0040] (3) The substrate is peeled off, and laser engraving is performed on the non-sponge surface to obtain a rough surface. Then 1.8 ...
Embodiment 3
[0044] The present invention builds superlubricating interface (such as figure 1 ), and in the external magnetic field
[0045] Create recoverable depressions that move transported droplets. The small-radius and fast-speed circular motion through the depression realizes the mixing and stirring of the droplets and speeds up the reaction rate. Specific steps are as follows:
[0046] (1) Take 20 grams of silicone oligomer, 2 grams of crosslinking agent, and 12 grams of iron powder and stir and mix evenly;
[0047] (2) Take an appropriate amount of the obtained mixture and add it dropwise to a custom-made mold of 12 square centimeters, let it stand for 30 minutes, pre-polymerize at 80 degrees Celsius for 30 minutes, then contact the 2 mm thick sponge substrate with it, and polymerize at 80 degrees Celsius for 8 hours, combine as figure 2 .
[0048] (3) The substrate is peeled off, and laser engraving is performed on the non-sponge surface to obtain a rough surface. Then 2.4...
