Molecular silicasol-based barrier coatings for organic electronics

Abstract

A solution-processable approach to designing molecular silicasol-based barrier coatings for organic electronics has been developed. The barriers are assessed by the optical calcium test and demonstrate water-vapor permeation rates of about 10^–2 g m^–2 day^–1. Silicasols are shown to be promising for the encapsulation of organic electronics devices, for which the resulting water-vapor permeation rates are sufficient (e.g., for organic field-effect transistors).
