摘要:In recent years, with the development of electronic equipment, fabricating a lightweight and effective absorber to prevent electromagnetic (EM) wave pollution has been an imperative mission. Among diverse innovative strategies, constructing a large interconnected conductive network has been an effective approach to dissipate the EM wave. Herein, Co/C hybrids with twisty carbon nanotubes (CNTs) were prepared from melamine-formaldehyde resin through a polymerization method together with a subsequent calcination process.. The resultant Co/C hybrids were strung into an interconnected framework by long and twist CNTs, which exhibited remarkable microwave characteristic at low loading content of 20 wt % in a wax matrix. The reflection loss (RL) intensity of 43 dB was achieved with an effective frequency bandwidth (RL < -10 dB) of 4.45 GHz at 1.85 mm. Such excellent absorbing properties at lower filler loading and thin thickness endow the Co/C hybrids with significant potential for application in attenuation EM wave energy.
