Comprehensive Study on the Reinforcement of Electrospun PHB Scaffolds with Composite Magnetic Fe3O4–rGO Fillers: Structure, Physico-Mechanical Properties, and Piezoelectric Response

“…64 Meanwhile, the deconvolution of the C 1s region for the newly developed Fe 3 O 4 −rGO composite uncovered all typical peaks of rGO (Figure 2C) such as C sp 2 , C sp 3 , C−OH, C−O−C, C�O, and C−OOH. 64,65 Aside from these results, the analysis of the O 1s region indicated the presence of a Fe−O peak from magnetite as well as functional groups C−O and C�O (Figure 2D). 65 The fitting of the N 1s region revealed two typical peaks from rGO corresponding to pyrrolic C and quaternary C for pristine rGO and Fe 3 O 4 −rGO composites (Figure 2E).…”

“…65 The fitting of the N 1s region revealed two typical peaks from rGO corresponding to pyrrolic C and quaternary C for pristine rGO and Fe 3 O 4 −rGO composites (Figure 2E). 65 To sum up, the XPS analysis confirmed the formation of magnetite particles on rGO flakes.…”

Electromechanical Performance of Biocompatible Piezoelectric Thin-Films

“…One study reported that the nanofillers at low concentration amalgamated with PVDF enhanced the d 33 coefficient. Such nanofillers were reported as carbon nanotubes (CNTs), graphene, metal-oxide based nanofillers, which demonstrate the enhanced piezoelectricity due to the nucleation of the polar piezoelectric β and γ phases [26,35,36]. There are many other important studies focused on the PVDF-TrFE piezoelectric applications in biomedical sensing and generators.…”

“…There are many other important studies focused on the PVDF-TrFE piezoelectric applications in biomedical sensing and generators. The important reason in the improvement of such properties is due to the variation in the electroactive phase content caused by nano-and micro-structuring of the PVDF-TrFE [35][36][37].…”

Ofloxacin Removal from Aqueous Media by Means of Magnetoactive Electrospun Fibrous Adsorbents

“…Examples include superparamagnetic fibrous adsorbents used in the removal of U(VI) [ 28 ], Eu(III) [ 29 ], Cr(VI) [ 30 ], arsenic ions [ 31 ], Congo red [ 26 ] and malachite green oxalate organic dyes [ 32 ], as well as antibiotics such as tetracycline [ 30 , 33 ], from synthetic aqueous media and urban wastewater (UWW). It was expected that the development of functionalized magnetic nanomaterials exhibiting high surface areas and high saturation magnetization such as magnetically functionalized graphene-based nanocomposites [ 34 ] would further promote the generation of highly effective magnetoactive adsorbents with potential to be used in water-remediation processes [ 35 , 36 , 37 , 38 , 39 ].…”
