FORMING METHOD OF CONDUCTIVE THIN FILM

摘要

<P>PROBLEM TO BE SOLVED: To provide a method of forming a conductive thin film for forming a stable conductive thin film comprising metal nano particles on a base material surface in a short time with ease. Ž<P>SOLUTION: The method of forming the conductive thin film includes a step in which the ink containing metal nano particles is applied on a substrate to form a thin film, and a step in which the thin film is acted with reducing agent to perform a reducing process. The metal nano particle containing ink is preferred to contain those in which metal nano particles coated with a protective agent containing alkyl group in straight chain or branch, with carbon numbers being 10-20, are dispersed in nonaqueous dispersion medium. The reducing agent is preferred to be used in the state of water solution of concentration 0.005-0.5 mol/l, and the reducing process to be performed in the temperature condition of 40-70°C.
