Ionic organic reagents and colloidal particles or nano-composite film made of a fiber, a metal ion detection film and manufacturing method thereof

摘要

PROBLEM TO BE SOLVED: To provide a metallic ion detecting material capable of easily detecting a metallic ion different in a type from a conventional colorimetric analysis material using an ion recognizing substrate joined to a polymer at an analysis site.;SOLUTION: This manufacturing method of a nanocomposite thin film of an ionic organic reagent and a particulate having electric charge of a nano-order, is constituted by filtering a generated nanocomposite dispersion liquid by a membrane filter by electrostatically attracting the bionic organic reagent by mixing an aqueous solution of the ionic organic reagent with a particulate dispersing liquid, or covering the filter with a nano-composite by being impregnated into the filter. This invention includes its nanocomposite thin film and the metallic ion detecting material. This invention can provide a stably held film type simple metallic ion detecting material by forming the ionic organic reagent as a thin film.;COPYRIGHT: (C)2008,JPO&INPIT
