1. A wear-resistant super-hydrophobic composite material, comprising
a substrate, and
a wear-resistant super-hydrophobic composite coating on a surface of the substrate;
wherein
the wear-resistant super-hydrophobic composite coating is prepared by curing a super-hydrophobic composite precursor;
the superhydrophobic composite precursor comprises a gel and an aligned carbon nanotube bundles-SiO2-coupling (ACNTB-SiO2-coupling) agent layer on a surface of the gel;
the gel comprises an epoxy resin, an amino-terminated hyperbranched polysiloxane, and an additive;
the additive is an ACNTB-SiO2-coupling agent, the ACNTB-SiO2-coupling agent is prepared by mixing and reacting aligned carbon nanotube bundles (ACNTB), an alkali, a solvent, and tetraethyl orthosilicate and then adding a silane coupling agent and continuing reacting; and
the ACNTB-SiO2-coupling agent layer is a suspension that comprises the ACNTB-SiO2-coupling agent and is coated on the gel.
