Abstract

The invention discloses an anti-fingerprint antibacterial film. The antibacterial film comprises a substrate layer and a hardened layer, the hardened layer comprises a nitrogen-doped titanium salt, the antibacterial film has a good antibacterial function and makes the film with an excellent anti-fingerprint effect, and the hardened coating layer contains a nitrogen-modified titanium dioxide photocatalyst with an antibacterial function. The antibacterial film has the advantages of simple structure, good wear resistance, good transparency, high hardness, strong adhesion, effectiveness in fingerprint proofing, antibacterial function, prevention of fingerprints from remaining on a screen, and great reduction of damages of bacteria to bodies. The invention also discloses a preparation method ofa hardening liquid used for the hardened layer.

Description

technical field [0001] The invention relates to the field of optical films, in particular to an anti-fingerprint antibacterial film and a preparation method of a hardening solution. Background technique [0002] With the rapid development of science and technology, the utilization rate of intelligent electronic communication equipment is getting higher and higher, which is full of people's life. However, during the use of the smart display, fingerprints are easy to remain on the surface, causing the surface to be dirty, and when the screen is scratched, it is prone to a large number of scratches, which will have a great impact on the appearance and normal use of electronic products. During the use of the screen, it is easy to be contaminated with pathogenic bacteria such as Staphylococcus aureus and E. coli, and the screen will have a certain temperature during use, which is more conducive to the reproduction of bacteria. It is easy to be infected with bacteria and affect p...
