Embodiment 1
[0034] Weigh 5g of indium-tin-bismuth alloy with a melting point of 60°C, 3.0g of polydimethylsiloxane (PDMS) prepolymer, 0.3g of curing agent, 3g of epoxy resin glue, and 100mL of tetrahydrofuran, and mix them directly in a 250ml beaker. At the same time, the beaker was heated in a water temperature ultrasonic cleaner at 75°C and ultrasonicated for 10 minutes to promote the liquefied indium-tin-bismuth alloy to be highly dispersed in the liquid into small droplets, and immediately placed the beaker in an ultrasonic cleaner filled with cold water to cool and continue Ultrasonication, stop the ultrasonication after the temperature of the mixture in the beaker drops and the highly dispersed indium tin bismuth alloy droplets solidify into a highly dispersed solid powder. Soak the pre-cleaned and dried 300-mesh 316 stainless steel mesh of 5 cm in length and width into the solution in the beaker for 3 minutes, take it out, drain the solution on the top of the beaker, and vacuum-dry ...
Embodiment 2
[0036] Weigh 5g of gallium-zinc alloy with a melting point of 81°C, 2g of perfluorooctyltrimethoxysilane, 3g of acrylate glue, and 100mL of N,N-dimethylformamide, and mix them together directly in a 250mL beaker. Heat in a water bath at 100°C and stir mechanically for 10 minutes to promote the highly dispersed liquefied gallium-zinc alloy into small droplets in the liquid. Immediately place the beaker in a water bath filled with cold water to cool and continue to stir until the temperature of the mixture in the beaker drops to a high degree of dispersion. The gallium-zinc alloy droplets are solidified into a highly dispersed solid powder and the stirring is stopped. Soak the pre-cleaned and dried polyurethane foam of 5 cm in length, width, and 1 cm in height into the solution in the beaker for 3 minutes, repeatedly squeeze the polyurethane foam during this period, drain the solution on the top of the beaker after taking it out, and place it in a preheated 75°C Vacuum-dry in a ...
Embodiment 3
[0038] The low-melting-point metal-modified superhydrophobic stainless steel mesh made in Example 1 is cut into a circle with a diameter of 4.2 cm, placed between two clamps, clamped and sealed, and the upper and lower ends of the clamp are connected to a glass tube with an outer diameter of 4.2 cm. The oil-water separation device is clamped vertically (oil with a separation density greater than water) or at an angle of 30° to the horizontal plane (oil with a separation density lower than water) on a solid iron stand, pour the oil-water mixture, and the oil will quickly pass through the stainless steel mesh and enter the lower part The receiver, while the water will stagnate in the upper glass tube. The low-melting-point metal-modified superhydrophobic stainless steel mesh prepared by the present invention can efficiently and rapidly separate oil-water mixtures including dichloromethane, chloroform, n-hexane, petroleum ether, isooctane, peanut oil, soybean oil, and corn oil, an...
