CLAY COMPOSITE COATING MATERIALS WITH HIGH GAS BARRIER PROPERTY AND TRANSPARENCY

Abstract

Transparent clay-based coating materials with high He-gas barrier property were developed using synthetic stevensite and methoxymethyl nylon. The coated film can be used in a roll installation and is resistant to humidity. The high He-gas barrier property was achieved by using clay nanosheets with a high aspect ratio and improved film formability. However, the haze of the coated film increased with increasing aspect ratio of the clay nanosheets.
