摘要
A novel iron-coated carbon fiber has been fabricated by electrochemical method. Magnetic properties, complex permeability, and complex permitivity have been measured. It is found that the sample has a low coercive force. By doping a few fibers to general absorbers (carbonyl iron), the complex permeability and permitivity of composites achieved a rise without the obvious increase of filling density. This result shows that the doping of fibers to general absorber will effectively decrease the thickness of the microwave absorption layer. (C) 2002 Elsevier Science B.V. All rights reserved.
