Abstract
The invention relates to the field of high polymer materials, in particular to an antibacterial blue light prevention film for a mobile phone and a preparation method thereof, wherein the antibacterial blue light prevention film comprises carbon quantum dots/strontium titanate, and the molecular formula of the strontium titanate is as follows: srTi 1‑ x A x O 3 The blue light preventing film prepared by the invention has excellent antibacterial effect and good antibacterial spectrum property, and has certain inhibition effect on common staphylococcus aureus, escherichia coli, streptococcus, mould and clostridium on a mobile phone.
Description
Technical Field
The invention relates to the field of high polymer materials, in particular to an antibacterial blue light prevention film for a mobile phone and a preparation method thereof.
Background
With the development of high technology, electronic products are more and more, no matter the old and the young have to play with mobile phones, and meanwhile, the group vision is continuously reduced, so that the biggest reason for the phenomenon is blue light emitted by the electronic products, especially the mobile phones.
The natural world has no independent white light, and the blue light and the green light are mixed to present white light. The green light and the yellow light have smaller energy, smaller stimulation to eyes, short blue light waves, high energy and larger damage to eyes, and the visible light emitted by various novel artificial light sources such as various computers, television screens, mobile phone screens, energy-saving lamps and the like contains a large amount of short wave blue light with irregular frequency, and the wavelength is between 400 and 500 nm.
Blue light can cause maculopathy of retina, and maculopathy almost becomes the first killer of full human vision, and short wave blue light has extremely high energy, can penetrate crystalline lens and reach retina. Blue light irradiation of the retina produces free radicals which lead to the decay of retinal pigment epithelial cells, which lead to the loss of nutrients to light-sensitive cells and thus to vision impairment, which is irreversible.
The blue light preventing film for mobile phone is one kind of eyesight protecting film developed for blue light radiation. The blue light blocking film can block short-wave blue light, plays a soft light source, reduces the effect on eye irritation, and the blue light blocking film commonly used at present is formed by adding a light stabilizer with yellow color into organic resin to block blue light, so that the blue light blocking film can be yellow, and when the blue light blocking film is used on a high-definition mobile phone screen, color deviation can be brought, and the product quality and the use experience are seriously influenced.
Disclosure of Invention
The invention aims to: aiming at the technical problems, the invention provides an antibacterial blue light prevention film for a mobile phone and a preparation method thereof.
The technical scheme adopted is as follows:
an antibacterial blue light preventing film for mobile phone comprises carbon quantum dots/strontium titanate.
Further, the molecular formula of the strontium titanate is: srTi 1-x A x O 3 X is 0.1-0.35, A is any one of Nb, al and In.
