Super-hydrophobic carbon-doped ceramic aerogel material and preparation method thereof
The invention discloses a super-hydrophobic carbon-doped ceramic aerogel material and a preparation method thereof, and belongs to the technical field of aerogel, and the preparation method of the super-hydrophobic carbon-doped ceramic aerogel material comprises the following steps: uniformly dispersing hydrophobic hexagonal boron nitride nanoparticles, epoxy resin, a curing agent and a diluent to prepare a hydrophobic coating; spraying hydrophobic paint on the surface of the rough S < i > C ceramic aerogel by using a spray gun, and curing at room temperature to obtain super-hydrophobic carbon-doped ceramic aerogel; graphite carbon is adopted to support a carbon aerogel skeleton, the roughness of the surface of the aerogel is increased through acid etching, the binding force between the aerogel and epoxy resin is enhanced, the epoxy resin generates strong cohesive force and adhesive force in the curing process so that the ceramic aerogel and hydrophobic particles can be tightly connected together, and the hydrophobic particles are tightly bonded together. The obtained aerogel has high strength and super-hydrophobicity, and has a good application prospect in a humid and hot environment.
