Title:
GAS-ABSORBING FILM
Document Type and Number:
WIPO Patent Application WO/2017/204222
Kind Code:
A1
Abstract:
This gas-absorbing film is formed from a resin mixture which contains a heat-resistant resin and an inorganic gas adsorbing material. A resin having a heat resistance of 200°C or higher, especially a resin having a heat resistance of 300°C or higher is used as the heat-resistant resin. In addition, it is preferable that an inorganic porous material, especially zeolite is used as the inorganic gas adsorbing material, since an inorganic porous material, especially zeolite has excellent absorbency of CO2 and hydrocarbon gases such as CH4 and C2H6. It is preferable that this inorganic gas adsorbing material has an average particle diameter of 10 μm or less. This inorganic gas adsorbing material is mixed with the heat-resistant resin, and is subsequently formed into a film. This gas-absorbing film is suitable for internal installation in a lithium ion battery or an electricity storage device, and for food packaging. This gas-absorbing film has good handling properties, and exhibits excellent absorbency of a carbon dioxide gas or the like after long-term storage.
