Hybrid multilayered films comprising organic monolayers and inorganic nanolayers for excellent flexible encapsulation films

Abstract

In the present study, we develop novel hybrid multilayered films films composed of organic monolayers of 4-mercaptophenol (4MP) and inorganic Al2O3 nanolayers for thin film encapsulation. The 4MP/Al2O3 multilayered films films achieved an excellent transmittance (>90%) and an ultralow water vapor transmission rate (2.32 × 10−7 g m−2 days−1), even retained the excellent barrier properties in 1000 times bending process. Inhibition of pinhole propagation and resistance to mechanical strain from organic monolayers with the help of inorganic nanolayers brought to such superior barrier performance in flexible devices, which can enhance the lifespan of the organic electronic devices.
