%L acta82464 %X Graphene and its derivatives have become the scientific community's focus due to their remarkable electronic, mechanical, and optical properties. In this work, we prepared two graphene-based materials, graphene oxide (GO) and electrochemically exfoliated graphene (EEG), and performed morphological and structural analysis. Both materials showed good dispersibility in water. GO is composed of mainly single- and few-layer graphene sheets, while EEG is predominately multi-layer graphene. EEG showed better thermal stability under nitrogen flow compared to GO. We also performed ElectroMagnetic Interference (EMI) shielding performance measurements of these materials. %O Bibliogr.: 318. p. ; ill. ; ĂśsszefoglalĂĄs angol nyelven %K ElektrokĂŠmia %D 2023 %J Proceedings of the International Symposium on Analytical and Environmental Problems %A StefanoviÄ Andjela %A Kepic Dejan %A HuskiÄ Miroslav %A Haddadi Kamel %A Sebbache Mohamed %A JovanoviÄ VuÄetiÄ Svetlana %A TodoroviÄ MarkoviÄ Biljana %I University of Szeged %P 314-318 %V 29 %T Measurement of EMI shielding performance of graphene oxide and electrochemically exfoliated graphene thin films %C Szeged
