Abstract
To develop novel microwave absorbing materials, polyaniline (PANI) composites filled with graphene was prepared, and the morphology, crystallographic structures and microwave parameters of the composites were investigated by SEM, XRD, FTIR and HP8722ES network analyzer. The uniform dispersion of graphene significantly enhanced the formation of conductive pathways in the PANI arrays and the interfacial affinity between PANI and graphene increases the number of conductive pathways of electron transfer. The composites show great microwave absorbing properties of −17dB. This study reveals that the PANI-Graphene composite is promising for applications as microwave absorbing material.
