Flexible Transparent Clay Films with Heat‐Resistant and High Gas‐Barrier Properties

This is the authors' abstract. We don't add key points for this paper.

Flexible transparent clay films with heat resistant and high gas-barrier properties are fabricated by using a simple casting procedure. The properties are as follows, lower than 0.1 cm3 20 μm m–2 day–1 atm–1 for oxygen permeability, over 90 % total visible-light transmittance, and heat durability up to 350 °C. The figure shows the transparency of the film before and after heat treatment at 350 °C for one hour.
