COMPOSITION FOR SHIELDING ELECTROMAGNETIC WAVE AND PRODUCTION METHOD THEREFOR AND FORMATION METHOD OF ELECTROMAGNETIC WAVE SHIELD USING THAT COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic wave shield formed by using a composition for shielding electromagnetic wave, and to provide an electromagnetic wave shielding structure having the shield formed therein that can maintain a high conductivity even after long time use and exhibits excellent stability over time.

SOLUTION: The composition for shielding electromagnetic wave is produced by dispersing metal nanoparticles into a dispersion medium, and the metal nanoparticles contain 75 mass% or more of silver nanoparticles. The metal nanoparticle has a carbon skeleton which is modified chemically with a protective agent of 3C main chain organic molecules, and the metal nanoparticles contain 70% or more of metal nanoparticles having a primary particle diameter in the range of 50-200 nm in number average.
