The piezoelectric response of electrospun PVDF nanofibers with graphene oxide, graphene, and halloysite nanofillers: a comparative study

Hybrid lead-free polymer-based nanocomposites with improved piezoelectric response for biomedical energy-harvesting applications: A review

“…Lead-free piezoceramic particles (BT, KNN) [48-51, 54, 55], metal oxide NPs (ZnO, MgO, TiO 2 ) [19,[56][57][58][59], CNTs [60][61][62][63][64][65], graphene and graphene derivatives such as rGO [27,66,67], hydrated ionic salts [68], nanoclays [69,70], and metal NPs (Ag, Pt) [71,72] have all proven to be highly efficient as nucleating fillers that can induce a polar electroactive phase without applying electrical polarization. By optimizing the concentration and uniformity of the distribution of the fillers in the polymer matrix, superior piezoelectricity and dielectric values are obtained.…”

Approaches for Increasing the β-phase Concentration of Electrospun Polyvinylidene Fluoride (PVDF) Nanofibers

“…Besides, the oxide particles such as zine oxide (ZnO) and [29][30][31][32][33][34][35] graphene oxide are commonly used to improve the properties of nanomaterials including PVDF nanofibers. Among the oxides, ZnO has drawn great interest for decades owing to the versatility, environmentally friendly, earth abundancy, and excellent electrical properties.…”

Improved uniaxial dielectric properties in aligned diisopropylammonium bromide (DIPAB) doped poly(vinylidene difluoride) (PVDF) nanofibers

“…DIPAB doped PVDF nanobers showed an enhanced dielectric constant in comparison to the previously reported dielectric constants for pure PVDF nanobers which were in the range of 11 to 18 at low frequencies. [31][32][33] Fig. 7(a) shows the variations in the dielectric constant of PVDF nanobers doped with varying ratios of DIPAB.…”
