Evolution of the Physical Properties of FeCl₃Filled Polystyrene Films

Structural, electrical and magnetic properties of polystyrene films filled with AgNO3–FeCl3 mixed fillers

“…The above assigned crystalline peaks can be attributed to the formation of clusters. This explanation agrees quite well with the ESR interpretation of the formation of aggregated Fe 3+ and the absence of isolated Fe 3+ [10,13,[22][23][24][25][26][27]. Generally, it is clear that at X ¼ 1%, the aggregation (clusters) is basically due to FeCl 3 filler, while at X ¼ 9%, the aggregation (clusters) is basically due to AgNO 3 filler.…”

“…9. This spectrum can be attributed to the hyperfine structure resulting from the interaction of the unpaired electrons with the nuclei of the virgin sample [10]. The ESR spectra of PS films filled with various mass fractions of (X)AgNO 3 (10ÀX)FeCl 3 are depicted in Fig.…”

“…Ferric chloride, FeCl 3 , with trivalent iron ions of 3d 5 electron configuration was selected as a filler due to its magnificent magnetic and electrical properties [3,4,[8][9][10]16]. Moreover, FeCl 3 has been reported to give the most stable material, an aspect of importance when considering applications [16].…”

“…Recently transition metal ions have been extensively used as fillers in organic polymers because of the partially filled d-electron shells of very interesting properties [3,4,[7][8][9][10][11][12][13][14][15][16]. Ferric chloride, FeCl 3 , with trivalent iron ions of 3d 5 electron configuration was selected as a filler due to its magnificent magnetic and electrical properties [3,4,[8][9][10]16].…”

Characterization, electrical and magnetic properties of PVA films filled with FeCl3–MnCl2 mixed fillers

“…Moreover, different polymers such as poly(vinylidene fluoride) PVDF, polystyrene PS and polymethyl methacrylate PMMA were magnetically studied by Tawansi et al [5,6,[8][9][10]35]. Various magnetic properties were obtained according to the polymer, the type of the filler and the filling level.…”
