| 摘要 |
The invention provides an antimicrobial composition which may be dispersed in a polymer to form a polymer composite and which comprises an antimicrobial coat of an aluminosilicate on the surface of silica gel, said aluminosilicate containing metal ions having microbicidal action. The composition is obtained by treating silica gel with an alkali solution and an aluminate solution to form a coat of aluminosilicate containing ion-exchangeable metal and treating the coat with a solution of a salt of a metal having microbicidal action. |
