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

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...

Description
Summary: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.
