Characterization of a passivation layer comprising MgOSiO₂ and ZrO₂

Abstract

Thin films with magnesium oxide (MgO) and silicon oxide (SiO 2 ) compounds mixed at various mixture ratios were deposited on flexible polyether sulfone (PES) substrates by an e-beam evaporator to investigate their potential for transparent barrier applications. In this study, as the MgO fraction increased, thin films comprising MgO and SiO 2 compounds became more amorphous, and their surface morphologies became smoother and denser. In addition, zirconium oxide (ZrO 2 ) was added to the above-mentioned compound mixtures, and the properties of the compound mixture comprising Mg-Si-Zr-O were then measured.

Enhanced Water Vapor Blocking in Transparent Hybrid Polymer–Nanocrystal Films

“…Metal or inorganic films can function as superior oxygen and moisture barriers. 3 However, their fabrication involves an expensive manufacturing process, such as atomic layer deposition or chemical vapor deposition, which are not cost-effective and challenging for large-scale manufacture. 4 Moreover, requirements of flexibility, strong adhesion, and transparency strongly limit their use; hence, polymer-based materials are commonly used for gas barrier applications in functional devices.…”

“…Highly efficient gas barrier materials are required for a wide variety of applications, from food and drug packaging to electronic displays, devices, and photovoltaic cells. , In particular, thin, flexible, and transparent coatings with excellent oxygen and moisture barrier properties are critical in photovoltaic modules and electronic devices, to ensure reliability and improve their life span.
