DIELECTRIC PROPERTIES CHARACTERISATION AND 3D VISUALIZATION OF NANO-CONDUCTIVE COMPOSITE

Autor/autori: Maria URSAN, George-Andrei URSAN

Rezumat: In aceasta lucrare este prezentat un material nanocompozit sub forma de film, format din polisulfona si magnetita 5%. Acestui material i-au fost analizate proprietatile dielectrice (constanta dielectrica, factorul de pierderi dielectrice, tangenta unghiului de pierderi sau factorul de disipare) cu ajutorul spectrometrului dielectric de la Novocontrol. In final este prezentata vizualizarea 3D a structurii acestui material, care a fost realizata cu ajutorul microtomografului SkyScan 1174.

Cuvinte cheie: material compozit nano-conductiv, proprietati dielectrice, vizualizare 3D,

Abstract: In this paper is presented a nanocomposite material on film form, consisting of polysulfone and 5% magnetite. For this material have been investigated the dielectric properties (dielectric constant, dielectric loss factor, loss angle tangent or dissipation factor) using a dielectric spectrometer from Novocontrol. Finally, a 3D visualization of the structure is made of this material, which was performed using Skyscan 1174 microtomograph.

Keywords: nano-conductive composite, dielectric properties, 3D visualization
