PS@TiO2 structured color film with non-iridescent effect as well as preparation method and application thereof

The invention provides a PS@TiO2 structured color film with a non-iridescent effect as well as a preparation method and application thereof, and the preparation method comprises: uniform particle sizeand monodisperse PS@TiO2 microspheres are firstly prepared by a soap-free liquid polymerization and mixed solvent method, the surface of the PS microspheres is coated with good sphericity degree TiO2nanoparticles with a diameter of about 8 nm uniformly, and a TiO2 shell layer having a thickness of about 10 nm is formed; the TiO2 shell layer is evenly mixed with a carbon black material to obtaina mixture, and the structured color film is obtained by spraying the mixture with a spray gun. The color of the film does not change with the change of the viewing angle, the color is stable to display and is not easy to fade; and the film has broad application prospects in the field of color display, and expands the types of amorphous photonic crystal structure color film materials. The preparation method has the advantages of simple preparation method, strong repeatability, environmental protection safety and non-toxicity; the spraying method has low requirements on a substrate and film coating environment, and is suitable for constructing the structured color film which does not change in color with the change of the viewing angle on various material surfaces, the spraying method can beused for preparing in a large area, and industrialization is easy to realize.

Footed negative pressure tea cup cover

The invention relates to a footed negative pressure tea cup cover, belonging to the technical field of tea cups. The footed negative pressure tea cup cover comprises a cup cover body (1) and a cup cover decoration (2) which are tightly combined. The footed negative pressure tea cup cover is characterized in that the cup cover body (1) and the cup cover decoration (2) are combined in a detachable and separable manner; and the cup cover body (1) is made from non-toxic food ware rubber. The invention overcomes limitation that the tea cup cover is dustproof only in the prior art and realizes the effects that the cup cover body (1) can generate a negative pressure suction force when the cup cover body (1) is slightly pressed during operation and negative pressure sealing and negative pressure fragrance keeping functions are created; the cup cover body (1) is adopted, thus matching universality of a cover and a cup is created; and when the cup cover decoration (2) is picked off from the cup cover body (1), the tea cup cover can be used as a negative pressure sealed ice basin cover, and versatility of the footed negative pressure tea cup cover is created. At least six small cylinders R are arranged at the cup cover body 1 at the top of a cup cover, the concave surface K of the cup cover is not polluted when the tea cup cover is laid flat, and the tea cup cover has a self antifouling function; and the cup cover decoration (2) can be made into animal modelling and fruit modelling artwork ornaments, and the whole footed negative pressure tea cup cover is a beautiful decorative tea cup cover.
