Abstract

The invention discloses a preparation method and application of an anti-blue-ray film. The method comprises the following steps: 1) preparing a composite microsphere having a core-shell structure; and2) carrying out mirror rolling or one-way hot-pressing on the prepared composite microsphere to obtain a function film having an anti-blue-ray effect. The composite microsphere having the core-shellstructure is formed by a core, a transition layer and a shell from the inside out in sequence. The core is made of a spherical material, which is uniform in size, and deviation of which is less than 10%. The size of the spherical material is in a submicron range, and specifically refers to microspheres in 150-200 nm, which has higher reflection for blue rays in 380-420 nm. The beneficial effects are that the method adopts a pure chemical process to endow the film with the characteristics of multiple functions, and especially in the optical property of the thin film, free regulation of the solar spectrum is realized, such as control of visible light and high barrier of near infrared; and the anti-blue-ray film can be widely applied to fields of buildings, cars, ships and electronics and thelike.

Description

technical field [0001] The invention relates to a preparation method and application of an anti-blue light film, belonging to the field of functional films. Background technique [0002] Photonic crystal material is a new type of optical material, which refers to the regular arrangement of regular materials to form an optical forbidden band. This optical forbidden band can realize high reflection of light waves of a certain wavelength, and then filter out our Unwanted light waves. [0003] Opal in nature is a natural photonic crystal material. Silicon oxide or other inorganic nano-microspheres form a regular close-packed structure inside opal through complex and long-term crustal movement. This regularly arranged structure can reflect the sun. The visible light in the light makes the natural opal stone have brilliant colors. Inspired by the structure of natural opal, researchers have prepared various artificial photonic crystals since the 1980s, among which composite photo...
