▎ 摘  要

NOVELTY - The device (100) has a drying graphene oxide material held in a containment structure (110). The containment structure is permeable to water vapor. A moisture indicating material changes color when a graphene is 90% saturated with water. The moisture indicating material is exposed to an environment inside of the containment structure. The moisture-adsorbing device comprises a protective seal (140) that reduces an amount of the water vapor entering the containment structure during storage. The protective seal is broken or removed before use. USE - Moisture-adsorbing device for use in a dry enclosure device (claimed). ADVANTAGE - The protective seal reduces the amount of the water vapor entering the containment structure during the storage. The device allows graphene oxide desiccant to provide enhanced adsorption at low and high relative humidity levels. The device allows an object into an internal dry environment to maintain or increase dryness of the object. DETAILED DESCRIPTION - The containment structure is a barrier to a passage of gas. An INDEPENDENT CLAIM is also included for a method for removing moisture from an internal dry environment of a dry enclosure device. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of a moisture adsorbing device including a transparent window and a moisture permeable orifice with a protective cover covering the orifice and a moisture indicating material mixed among graphene oxide powder.
