Abstract

The invention relates to a PET-based protective film with a blue light adjusting function. The PET-based protective film comprises a blue light adjusting functional layer arranged on a PET base layer; the material of the blue light adjusting functional layer is obtained by compounding a blue light absorbing material and polymethyl methacrylate, and the blue light absorbing material is riboflavin composite mesoporous alumina / cerium oxide nanospheres. Self-made riboflavin composite mesoporous alumina / cerium oxide nanospheres are used as a blue light absorbing material and are mixed with polymethyl methacrylate to prepare the blue light adjusting functional layer, and the blue light adjusting functional layer can adjust and absorb blue light within the wavelength range of 300-500 nm to a certain extent. The protective film also has better light transmission on the premise of not adding an anti-reflection agent, and the blue light adjusting function layer still has excellent performance under the condition of lower thickness, so that the protective thickness is further reduced, and the prepared protective film is lighter and thinner.

Description

technical field [0001] The invention relates to the field of PET-based protective films, in particular to a PET-based protective film with a blue light regulating function. Background technique [0002] In visible light, blue light is the light closest to ultraviolet light and has the highest energy. Its wavelength is between 300 and 500 nanometers, and it appears blue in the light perception of the human eye. A large number of reports have shown that long-term exposure to severe blue light can lead to visual impairment, macular degeneration, and damage to the retina. In mild cases, red eyes, dry eyes, dry eyes, blurred vision, visual fatigue, and head, muscles, shoulders, and cervical spine can also occur. Pain and other symptoms. As the background field of liquid crystal displays, blue light is widely used in various electronic products, such as computers, smart phones, tablet computers, and TV LED displays. With the popularity of these electronic products and penetration...
