Study of Microwave Absorption Properties of Nickel-doped Ordered Mesoporous Carbon/Polyaniline Composite

Nickel-contained ordered mesoporous carbons(OMC-Ni) and HCl/LAS-doped polyaniline(PANI) composites were fabricated,and the microwave absorption properties of the composite were investigated via transmission line theory in the range of 2-18 GHz.It is found that both the increase of Ni loading contents in OMC and the change of PANI content in OMC-Ni/PANI can improve the absorption properties obviously.Meanwhile,the effective absorption is closely related with the matching thickness in the case that the effective bandwidth(≤ -10 dB) of OMC-Ni0.05/PANI is 5.0 GHz(10.7-15.7 GHz) when d is 1.9mm.
