The invention relates to a
cellulose /
titanium dioxide / silica
aerogel and a preparation method thereof. The method comprises the steps such as
cellulose sol preparation, nano-grade
titanium dioxide
surface loading, silica
surface coating, curing, aging, hydrophobizing, bonding forming,
drying treatment, and the like. According to the invention, nano-grade
cellulose is adopted as a core, and is loaded with nano-grade
titanium dioxide; a silica layer is coated; and the steps such as curing, aging, hydrophobizing, bonding forming,
drying treatment, and the like are carried out, such that the cellulose /
titanium dioxide / silica
aerogel is obtained. The
aerogel has the performances such as flexibility, high strength, bacterium resistance,
ultraviolet resistance,
odor-removing function, warm-keeping function,
thermal insulation, and sound insulation. The aerogel can be widely applied in the fields such as thermal underwear,
body armor, insulation materials, pressure-resistant materials, special coatings,
aerospace materials, and the like.
