Estimating the term…
The present invention relates to a fluorine-based polymer coating film, an optical substrate comprising same, and a method for manufacturing the optical substrate, and provides a fluorine-based polymer coating film which is formed from fluorine-based polymer nanoparticles coming in contact and being bound to each other, and which is coated on a substrate to improve infrared transmittance. The fluorine-based polymer coating film according to the present invention has improved infrared transmittance, and since the size of the fluorine-based polymer nanoparticles is controlled to control the ultraviolet-infrared transmittance, transmission wavelength selectivity can be improved.
A method of improving transmittance of an optical substrate in an infrared region comprising coating a fluorine-based polymer coating film on the optical substrate, wherein the fluorine-based polymer coating film is formed from fluorine-based polymer nanoparticles coming in contact and being bound to each other, and thereby improving transmittance of the optical substrate in the infrared region,
