High-performance transparent moisture barrier

Tuesday, 3 April 2018

Topic of a recently published paper was the fabrication of a high perfornace moisture barrier material (SC nanocomposite) by using surface-modified bentonite clay (SC) as nanofiller and glycidyl silane as a surface-modifier/binder.

Scientists report the facile fabrication of transparent and high-performance moisture barrier material (SC nanocomposite) using surface-modified bentonite clay (SC) as nanofiller and glycidyl silane as a surface-modifier/binder via simple, cost-effective and mass-producible process. SC is synthesised using a base-catalysed sol-gel process; their hydroxyl surfaces are decorated with glycidyl ligands to endure the densely stacked structure and high clay content in the final nanocomposite.

Encapsulation of light-emitting devices

The SC nanocomposite barrier exhibits high optical transparency (>90), dense multi-stacked clay structure, and considerably enhanced moisture barrier performance. The scientists discuss the fabrication and physical properties of the SC nanocomposite. To assess the applicability of the nanocomposite as a high-performance barrier material in practical applications, typical organic light-emitting devices are encapsulated, and their lifetime is evaluated.

The study is published in: Progress in Organic Coatings Volume 118, May 2018, Pages 66-71.
