Investigation of EMI-shielding properties of buckypaper manufactured with an easily scalable method.

This paper proposes a simple and easily scalable method for the production of buckypapers. Buckypapers are made by airbrushing a suspension of dispersed SWCNTs onto a PET substrate, followed by solvent evaporation. The process does not require sophisticated equipment and is technologically straightforward.

Graphene passivation effect on copper cavity resonator preserves Q-factor.

Proposed resonator design and measurement technique is a promising solution to estimate the value of materials surface conductivity. In the developed device, there are no mechanical connections, that interrupt the flowing microwave currents, which eliminates losses due to poor metal contact and related measurement errors. The main losses (60%) in the resonator are concentrated in a small sample under study - resonance element sample, which ensures high sensitivity to changes in surface conductivity.
