Description

Anti-fog type composite electrochromic sheet

This creation is about an electrochromic sheet, especially an anti-fog composite electrochromic sheet that has an anti-fog function and can form a spherical structure.

The electrochromic element is a multi-layer electrochemical device, in which when a voltage is applied, the substance in the element undergoes a reversible reaction of oxidation or reduction to cause a color change phenomenon. The coloring and decoloring reaction of the electrochromic element is achieved through the driving voltage. Electrochromic elements are widely used in daily life. For example, they are installed on the protective shields of eyeglass lenses or helmets. The light transmittance can be adjusted according to specific external environmental conditions to reduce light damage and protect the eyes.

In addition to improving the optical properties of lenses or protective shields by providing electrochromic films, there is an urgent need to overcome another problem in the use of lenses: fog condensation. Moisture in the air will condense into water droplets when it comes in contact with a lower temperature surface. When wearable lenses such as helmets or goggles condense on the surface of the lens due to the moisture in the breath of the wearer or the heat evaporated from the body. Small water droplets accumulate on the surface of the lens and scatter the incident light in any direction, causing the eyes to be unable to see the image clearly through the lens. This state is called fogging. The sight shielding caused by fogging causes inconvenience to the use of the lens and even leads to safety. Sexual issues. The anti-fog method of the lens can be to apply anti-fog products such as anti-fog patch, anti-fog spray, anti-fog film, etc. to the outside of the lens, that is, to apply anti-fog products to the lens by attaching, spraying, coating, etc. Externally, or by changing the characteristics of the substrate on the surface to be anti-fog, it is difficult for water droplets to accumulate on the surface of the lens to achieve the anti-fog effect. At present, it is known that a multilayer film formed by glass and polymer nanoparticles is used to form a porous network of glass nanoparticles through a special process. When water droplets begin to condense on the surface coated with glass nanoparticles, water molecules It will be absorbed by the hydroxyl groups on the nanoparticle, allowing the water molecules to evenly enter the porous layer, preventing the formation or accumulation of small water droplets on the anti-fog surface.

The conventional anti-fog lens has many limitations, such as: the durability of the anti-fog effect. For example, the anti-fog coating or spray on the lens may fall due to friction and other factors, losing its anti-fog function, and the attached anti-fog film It uses cellulose acetate, which has a soft texture and will rebound and deform after a period of time. Therefore, the anti-fog effect of conventional anti-fog lenses has poor durability; image distortion problems, such as most lenses are spherical lenses, However, the conventionally attached anti-fog film is flat, causing an uneven air gap between the lens layer and the anti-fog film layer, resulting in image distortion problems such as distortion of light transmission and distortion of the line of sight; cost issues, such as conventional It is known that the discoloration or UV resistance treatment of the anti-fog lens is to directly add a color change agent or an ultraviolet absorber on the lens layer, and the production cost is relatively high.

As far as lenses or protective shields are concerned, blocking light damage by electrochromic devices and preventing fogging by anti-fog technology are important lens functions for the user's eye care and safety. However, most conventional lenses only have one of the two functions. Even if the anti-fog sheet and the electrochromic sheet are used in combination, the current technology stays in a layered multi-layer structure, and an integrated anti-fog and electrochromic composite structure has not been developed. The conventional layered structure has complex structures , The resulting lens is bulkier and consumes more materials.
