Investigation of different graphite morphologies for microwave absorption at X and Ku-band frequency range

The different graphite morphologies, like graphite intercalation compound (GIC), expanded graphite (EG), and exfoliated graphite (ExfG), were investigated as microwave absorbing materials (MAMs). The modification of the GIC was carried out in two independent parts, consisting of heat treatment and subsequent ultrasound agitation, forming the EG and ExfG, respectively. The surface morphology and structural characterization were investigated using...
