Title:
ANTIMICROBIAL, ANTIVIRAL AND/OR ALGAE-PROOFING MATERIAL COMPRISING INORGANIC-ORGANIC HYBRID COMPOUND, AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/021106
Kind Code:
A1
Abstract:
In conventional types of antimicrobial, antiviral and/or algae-proofing materials wherein active ingredients are fixed to a solid material, there have been some types in which active ingredients are kneaded into an ordinary plastic (organic polymer). However, this approach has a disadvantage that active ingredients in superficial areas are easily eliminated, while the active ingredients embedded inside thereof fail to sufficiently act. The present invention pertains to an antimicrobial, antiviral and/or algae-proofing material which is obtained by fixing an active ingredient which is silver or copper metal or a compound thereof on an inorganic-organic hybrid compound in which an inorganic oxide or a derivative thereof is chemically bound to an organic polymer having a hydroxyl group. This hybrid compound possesses both water-resisting and water-absorbing properties, and the active ingredient that is stably fixed thereon is in the form of a fine and highly active particle such as nanosized particle. Thus, it is possible to obtain a highly effective antimicrobial, antiviral and/or algae-proofing material that does not result in unnecessary elimination or release of the active ingredient, and that also enables full use of the total amount of the fixed active ingredient.
