Embodiment 1
[0029] First, the cleaning of the melamine sponge: soak the melamine sponge at 50°C with a concentration of 0.5mol L -1 Hydrochloric acid aqueous solution was washed for 3 hours, washed with deionized water or distilled water or hot water until neutral, and then dried; then, PDMS loading: soak the cleaned melamine sponge in PDMS alkane solution, wherein PDMS accounts for 1% of the alkane mass , the curing agent accounted for 1% of the mass of PDMS, and dried at 60°C to obtain PDMS-loaded melamine sponge; finally, the PDMS-loaded melamine sponge was placed in a tube furnace at 600°C for 0.1h, and then carbonized at a high temperature under the protection of an inert gas , the PDMS-structured superhydrophobic melamine sponge carbon material can be obtained. The alkane is at least one of pentane, hexane, cyclohexane and octane.

Embodiment 2
[0033] First, the cleaning of the melamine sponge: soak the melamine sponge at 10°C with a concentration of 5mol L -1 Hydrochloric acid aqueous solution was washed for 5 hours, washed with deionized water or distilled water or hot water until neutral, and then dried; then, PDMS loading: soak the cleaned melamine sponge in PDMS alkane solution, wherein PDMS accounts for 5% of the alkane mass , the curing agent accounts for 1% of the mass of PDMS, and it is dried at 80°C to obtain a PDMS-loaded melamine sponge; finally, the PDMS-loaded melamine sponge is placed in a tube furnace at 400°C to maintain a constant temperature for 2 hours, and is carbonized at a high temperature under the protection of an inert gas. The superhydrophobic melamine sponge carbon material constructed by PDMS can be obtained.
Embodiment 3
[0035] First, the cleaning of the melamine sponge: soak the melamine sponge at 70°C with a concentration of 0.1mol L -1 Hydrochloric acid aqueous solution for 0.5h, washed with deionized water or distilled water or hot water until neutral, then dried; then, PDMS loading: soak the cleaned melamine sponge in PDMS alkane solution, wherein PDMS accounts for 0.1% of the alkane mass %, the curing agent accounts for 20% of the quality of PDMS, and is dried at 40°C to obtain a PDMS-loaded melamine sponge; finally, the PDMS-loaded melamine sponge is placed in a tube furnace at 900°C to maintain a constant temperature for 0.05h, and is heated at a high temperature under the protection of an inert gas. After carbonization, the superhydrophobic melamine sponge carbon material constructed by PDMS can be obtained.
