The electromagnetic interference(EMI) shielding effectiveness(SE) of the graphene sheets/polyaniline(GSs/PANI) composite in different contents of GSs was investigated.The high crystalline GSs were prepared by DC arc-discharge method.The GSs/PANI composites were synthesized by an alcohol-assisted dispersion and pressing process.Compared with the pure PANI materials' Raman spectra,the GSs/PANI composites show the decrease of the characteristic peak intensity or a red shift of the peak,which is induced by the ...
