摘要：
Composite materials (CMs) based on epoxy resin and functionalized thermoexfoliated graphite (TEG) were prepared. The composition of functional groups at the TEG surface was characterized by FTIR spectroscopy. It was found that some of CMs with pristine TEG have high shielding efficiency in the region of electromagnetic radiation frequency from 25.5 to 37.5GHz. But the main disadvantage of these CMs is their high porosity and heterogeneity that makes impossible to obtain the stable shielding characteristics for thin sample. However, CMs contained functionalized TEG are sufficiently homogeneous and allow purposefully regulate their electrical and shielding properties by changing TEG content.
