Description

Optical device with hydrophilic self-cleaning function

Technical Field

Background

The PET film has good insulativity, low thermal shrinkage rate, good mechanical property, high and low temperature resistance and good chemical resistance, and can be widely applied as a display screen protective film, a film window, an instrument panel protective film, an automobile glass adhesive film and a building glass adhesive film.

PET films for display screen protective films and windows have high requirements on light transmittance. In many application scenarios of displays or windows, the light transmittance is greatly affected by the surface contamination of the film.

A large portion of the surveillance cameras are installed in outdoor environments. In the open air, two factors affect the definition or imaging effect of the camera. Firstly, the dust of deposit forms under the effect of condensation and adheres to firm dirty layer on the camera lens safety cover, influences the lens safety cover light transmissivity, leads to the formation of image fuzzy. In rainy days, raindrops are hung on the outer surface of the camera lens protective cover, so that light is distorted or bright spots are formed. In order to solve the problems, a hydrophobic coating is added on the outer surface of the camera protection cover. However, the effect of the hydrophobic coating in practical application is not satisfactory. On one hand, the hydrophobic coating is easy to adsorb dust, and the hydrophobic surface loses hydrophobicity after being shielded by the dust; on the other hand, a hydrophobic surface works well when faced with large water droplets, but fine water droplets remain hanging on the surface. Therefore, the camera of the hydrophobic surface lens protection cover faces blindness risk on a rough rainy day.
