Title:
GAS ADSORBING MATERIAL AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JP3525804
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gas adsorbing material with the pore diameter and/or adsorptivity controlled in accordance with the kind of a gas to be adsorbed and its production method.
SOLUTION: In the production of a gas adsorbing material adsorbing a gas into the pore, the adsorbing material is exposed to a plasma atmosphere to enlarge the pore, and the pore diameter is adjusted in accordance with the kind of the gas to be adsorbed. In this method, graft polymerization is brought about in the pore to decrease the effective diameter of the pore, and the effective diameter is adjusted in accordance with the gas to be adsorbed. A functional group adsorbing the gas is preferably imparted to the graft polymerization.
