▎ 摘  要

NOVELTY - Electromagnetic wave absorbing material is prepared by covering surface of carbon material with carbon nanostructure having graphene structure, and the carbon nanostructure does not contain metal element. USE - The wave absorbing material is in electromagnetic wave absorbing resin molded portion including automobile emblem and/or automobile bumper, for removing electromagnetic wave noise, and used in personal computer and mobile telephone, and used as noise suppression sheet. ADVANTAGE - The wave absorbing material efficiently absorbs electromagnetic wave, is economical and lightweight, has high strength, does not contain metal element, suppresses electromagnetic noise that causes malfunction of sensing device, ensures excellent electromagnetic wave absorption capability, high mechanical capability and high moldability, and efficiently absorbs electromagnetic wave having high frequency band of 45-100 GHz. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electromagnetic wave absorbing resin molded portion comprising electromagnetic wave absorbing material present in resin base material.
