Investigation of photocatalytic performance of single layer superhydrophilic film: TEOS/PF‐127

Abstract

AbstractMultifunctional antireflective coatings (ARC) have great importance in various applications such as optical devices, flat panel displays, solar cell devices, and so on. Here in this work, highly transparent superhydrophilic film was developed on a cleaned glass substrate by depositing porous TEOS/PF‐127 using the spin coating technique. The coating shows a maximum transparency of 95% in the visible region (400–800 nm). The morphology and porous nature of the prepared sample was analyzed using FESEM and BET analysis respectively. The prepared film exhibited a water contact angle of 9° ensures its superhydrophilic nature. It is also noteworthy that TEOS/PF‐127 coating possesses photocatalytic activity by showing good photo degradation against MB (Methylene Blue) dye under UV‐B (280–315 nm, 50 W) and halogen (340–850 nm, 50 W) light irradiation. The present work provides a simple cost‐effective method to enhance the optical transparency of the glass substrate along with good self‐cleaning properties via photocatalytic activity.
