ELECTROMAGNETIC WAVE ABSORBING SHEET

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic wave absorber capable of dealing with absorption of electromagnetic waves of several GHz to several dozens of GHz. SOLUTION: An electromagnetic wave absorbing sheet contains a carbon nano-coil and a resin, wherein (1) the carbon nano-coil has an average coil length of≥1μm and <100μm, an average coil diameter of≥1 nm and <1μm and an average coil pitch of≥1 nm and <1μm and (2) the carbon nano-coil is contained in a ratio of 1 to 10 pts.wt. based on 100 pts.wt. of the resin.
