Abstract:
1. A method of preparing a composite configured to release refrigerant therefrom comprises: providing a substrate material comprising polarized fibers; bonding on the surface thereof a metal compound comprising one or more metal salts, or a metal hydroxide or combinations thereof; absorbing a polar gaseous refrigerant on said metal salt or metal hydroxide; forming layers of said metal compound bonded substrate material; and sealing at least one layer of said substrate material or the exterior surfaces of said composite with a coating composition configured to prevent release of internal gaseous refrigerant therethrough at ambient temperature and pressure and breached to allow penetration and release of internal gaseous refrigerant therethrough from the composite interior at a total internal gas pressure of 15% or more above exterior ambient or atmospheric pressure.
