Title:
WEAR-RESISTANT SUPER-HYDROPHOBIC COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/073277
Kind Code:
A1
Abstract:
A wear-resistant super-hydrophobic composite material and a preparation method therefor. The wear-resistant super-hydrophobic composite material consists of a substrate and a durable super-hydrophobic composite material coating layer on the surface of the substrate; the durable super-hydrophobic composite material coating layer is obtained by curing a precursor for the super-hydrophobic composite material coating layer; the precursor for the super-hydrophobic composite material coating layer consists of a gel and an ACNTB-SiO2-coupling agent layer on the surface of the gel; the gel consists of an epoxy resin and amino-terminated hyperbranched polysiloxane, or consists of an epoxy resin, amino-terminated hyperbranched polysiloxane and an additive; and the additive is an ACNTB-SiO2-coupling agent and/or diglycidyl-ether-terminated polydimethylsiloxane. The wear-resistant super-hydrophobic composite material has a water contact angle higher than 160° and more than 250 friction cycles.
