Abstract
A gas containment system can include a gas barrier layer forming a capsule. The gas barrier layer can be made up of a particulate swelling clay, a non-swelling particulate material mixed with the particulate swelling clay, water, and a water-soluble polyol. The water can hydrate the particulate swelling clay and form a continuous liquid phase in the gas barrier layer. The water-soluble polyol can be dissolved in the water. The gas containment system can further include a gas retained inside the capsule.
