ARTICLE HAVING NOBLE METAL PARTICLE ON BASE MATERIAL SURFACE, LAMINATE AND METHOD OF MANUFACTURING THEM

摘要

<P>PROBLEM TO BE SOLVED: To provide an article having many noble metal particles a part of which is buried in a base material on the surface of the base material and all of which are never buried in the base material, a method of easily manufacturing the article and a method of manufacturing a laminate on which a metal coating film having thickness of 10-200 nm is arranged on the surface of the noble metal particle of the article having the noble metal existing on the surface of the base material. Ž<P>SOLUTION: The particle having the noble metal particles existing on the surface of the base material is manufactured through a step of immersing the base material in a noble metal sol; and a step of heating the base material at a temperature equal to or above the glass transition point of the base material and equal to or below the molting point in the air or under an inert gas atmosphere. The laminate is manufactured by forming the metal coating film on the nobel metal particle surface by electroless plating method. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
