In the present investigation, synthesis of composites of Poly Aniline (PAni) and reduced graphene oxide (RGO) with different loading of 0.25 wt%, 0.5 wt.% and 1 wt.% have been prepared using microwave heating method. UV-Visible absorption spectroscopy indicates the formation of some sort of chemical interaction between RGO and PAni. EMI shielding measurements done using network analyzer show the enhancement in effective shielding absorbance upto -25 dB with loading of 1 wt.% loading of RGO in PAni in frequency region of 3-12 GHz.
