The invention discloses a high-transparent ultraviolet separation ceramic-imitating flexible nanometer composite membrane material and a preparation method thereof and belongs to the field of nanometer composite materials. The composite membrane material comprises 20-85 wt% of core-shell nanometer particles and 15-80 wt% of polymer macromolecules. The composite membrane material is prepared through in situ polymerization which includes two steps of phase transfer of nanometer particles and bulk polymerization of the nanometer grains in polymer monomer. The nanometer grains are transferred to the polymer monomer from initial dispersoid through a method of solution phase transfer, and then the high-transparent ultraviolet separation ceramic-imitating flexible nanometer composite membrane material is prepared through thermal initiation polymerization or ultraviolet light initiation polymerization. The nanometer composite membrane material is high in transparency, has good thermal stability, strong ultraviolet shielding capacity and certain flexibility, can be used for manufacturing transparent optical devices, uvioresistant devices, special light control devices and the like.
