Claim 8:
9. The superhydrophobic functional nanofluid according to claim 8, wherein a method for preparing the superhydrophobic functional nanofluid comprising:
Step 201, mixing superhydrophobic nanoparticles with an ethanol solution, and adding water to obtain a solution I; wherein the superhydrophobic nanoparticles including SiO2 and a fluorine-containing long chain grafted on the surface of SiO2, wherein the fluorine-containing long chain is a structural unit provided by heptadecafluorodecyltrimethoxysilane;
Step 202, dissolving sodium alpha-olefin sulfonate and lauramidopropyl betaine in water, performing mixing, and adding the obtained mixed solution into the solution I to obtain a solution II;
Step 203, subjecting the solution II to ultrasonic dispersion treatment under the heating condition to obtain the superhydrophobic functional nanofluid.
