Hybrids of glass fibers coated with carbon nanotubes and nickel for high?performance electromagnetic wave absorption composites

To expand the application of insulating glass fiber (GF) in field microwave absorption, one type GF hybrids with carbon nanotubes (CNTs) and nickel (Ni) was successfully synthesized by chemical vapor deposition electroless plating methods. By changing reaction conditions, morphology including CNT's length, growth density, Ni?s thickness could be adjusted. The as-produced were used as multifunctional reinforcement to fabricate epoxy composites. dielectric properties composites particularly measured from 1 18 GHz. It found that variation structure significantly changed tested frequency range. Furthermore, analytical simulation work based on experimental results conducted for optimizing structural parameters multilayered showed best reflection loss ?60 dB a ?10 range 5.6 GHz obtained an absorber triple-layered composed GF-CNTs/epoxy different CNT contents GF-CNTs@Ni/epoxy. Thus, proposed hybrid method might quite efficient developing can achieve high-performance electromagnetic absorbing.
