Title:

METAL NANOPARTICLE COMPOSITE AND PROCESS FOR PRODUCTION THEREOF

Document Type and Number:

WIPO Patent Application WO/2011/108342

Kind Code:

A1

Abstract:

A metal nanoparticle composite which is provided with a matrix resin layer and metal nanoparticles immobilized in the matrix resin layer and which has the following characteristics: (a) the metal nanoparticles are particles obtained by heat-reducing metal ions or metal salts which are contained in either the matrix resin layer or a precursor resin layer thereof; (b) the metal nanoparticles are present within a region extending from the surface of the matrix resin layer to a depth of at least 50nm; (c) the particle diameters of the metal nanoparticles fall within the range of 1 to 100nm with the mean particle diameter being 3nm or more; and (d) the spacing between adjacent metal nanoparticles is equal to or larger than the particle diameter of the bigger of the adjacent metal nanoparticles.
