Abstract

An inorganic porous crystals-hydrophilic macromolecule composite comprising a hydrophilic macromolecular substrate containing the inorganic porous crystals in its inner matrix, production method thereof and use thereof. The present invention affords an inorganic porous crystals-hydrophilic macromolecule composite comprising the inorganic porous crystals held in the inner matrix of the hydrophilic macromolecular substrate. This composite is particularly superior in adsorption of metal ion, specifically silver and copper ions, and the metal-holding inorganic porous crystals-hydrophilic macromolecule composite showed noticeably strong adsorption of hydrogen sulfide and the like, so that it can be used as a deodorizer, antimicrobial material and freshness retention material for fruits and vegetables.
