Process for the preparation of broadband antireflection film and the broadband antireflection film prepared therefrom

摘要

A broadband anti-reflection film manufacturing method and an anti-reflection film manufactured by the same are provided to form plural pores inside the anti-reflection film by condensing water drops. A high-molecular material is dissolved in a resolvent having a low boiling point, so that high-molecular solution is obtained. The high-molecular solution is coated on a substrate in a high-humidity atmosphere. The high-molecular material is an atypical transparent high-molecular agent. The high-molecular material is selected from a group consisting of an acryl-group polymer, a cellulose-group polymer, a styrene-group polymer, a polysulfone-group polymer, a fluor-group polymer, and mixtures thereof. The boiling point of the low-boiling point resolvent lies between 40 and 100‹C.
