Abstract

An anti-blue light / color-changing dual-function coating optical material and a preparation method thereof, the dual-function coating optical material includes an optical substrate, an anti-blue light coating and a photochromic coating. The anti-blue light coating is doped with polyurethane / light absorber / titanium oxide nanocomposite microspheres, which has a three-layer composite core-shell structure, the core is titanium oxide nanospheres, the middle layer is light absorber, and the outer shell is polyurethane. The anti-blue light coating has a blocking spectral range extending from the ultraviolet spectral region to the blue light spectral region, and has the performance of distinguishing absorption of blue light in different bands while maintaining a high transmittance. The anti-blue light coating is matched and functionally integrated with the photochromic coating material, which can automatically adjust the transmittance according to the intensity of the light. By selectively passing the beneficial light and cutting off the harmful light, the brightness can be controlled and the light can be transmitted on demand.

Description

technical field [0001] The invention belongs to the technical field of light-absorbing materials, and in particular relates to an optical material with specific absorption for different wavelengths in the 280-450nm spectral region and a preparation method thereof. Background technique [0002] As we all know, ultraviolet rays can damage human eyes. In addition, blue light in visible light can also cause damage to eyes. As part of visible light, blue light has extremely high energy, and its wavelength range is between 400 and 500nm. With the widespread popularization of electronic products such as computers, mobile phones, and ipads, unnatural light with blue light as the main body will cause irreversible damage to human eyes. Damage, causing dry eyes, fatigue, tearing, accelerated myopia, macular area disease and other problems. According to the orange warning issued by the World Health Organization (WHO) at the end of 2009: the potential invisible threat of blue light to h...
