“…The electrically activated P(VDF-TrFE) lter demonstrates that the ltering efficiencies were over 88% aer polarization and 94% aer tribo-electrication. Liu et al 32 added graphene into P(VDF-TrFE) by the solution casting method. When the additions of graphene were low, there was no effect on the crystallinity degree and open-circuit voltage of the composites increased.…”

“…In particular, Poly(vinylidene fluoride) [PVDF], a semi-crystalline fluorinated polymer has been studied extensively as a ferroelectric material, demonstrating five different crystal phases (α-phase, β-phase, α]-phase γ-phase, ε-phase, and δ-phase) (Cui et al, 2015). Among these, β-phase rich PVDF formulations have received much attention due to their pyroelectric and piezoelectric properties (Wu et al, 2019). Although β-phase crystalinity in melt or drop-casted PVDF is relatively low, multiple studies have reported that post-processing approaches can increase the formation of the β-phase content in PVDF (Gregorio, 2006; Martins et al, 2014; Cui et al, 2015).…”

Analysis of the cellular response to piezoelectric materials has been driven by the discovery that many tissue components exhibit piezoelectric behavior ex vivo . In particular, polyvinylidene fluoride and the trifluoroethylene co-polymer (PVDF-TrFE) have been identified as promising piezo and ferroelectric materials with applications in energy harvesting and biosensor devices. Critically, the modulation of the structural and crystalline properties of PVDF-TrFE through annealing processes and the addition of particulate or fibrous fillers has been shown to modulate significantly the materials electromechanical properties. In this study, a PVDF-TrFE/boron-nitride nanotube composite was evaluated by modulated differential scanning calorimetry to assess the effects of boron nitride nanotube addition and thermal annealing on the composite structure and crystal behavior. An increased beta crystal formation [f(β) = 0.71] was observed following PVDF-TrFE annealing at the first crystallization temperature of 120°C. In addition, the inclusion of boron nitride nanotubes significantly increased the crystal formation behavior [f(β) = 0.76] and the mechanical properties of the material. Finally, it was observed that BNNT incorporation enhance the adherence and proliferation of human tenocyte cells in vitro .

“…1. XRD of pure PVDF shows a strong peak at 2h = 20.37°that attributed to b-phase of PVDF related to the relatively high crystallinity of PVDF [39,40]. XRD patterns of PVDF scattered by different ratios of (Ag@Se) nanocomposites shows decreasing in intensity of the strong peak at 2h = 20.37°that continuous in decreasing by increasing the ratios of (Ag@Se) from 1(Ag@Se)@PVDF sample to 3(Ag@Se)@PVDF sample.…”

Several ratios of silver/selenium (Ag/Se) nanoparticles generated via laser ablation were used to create nanocomposite scaffolds based on polyvinylidene difluoride (PVDF). XRD, FTIR, and HR-TEM were used to examine the nanocomposite membrane that were created. XRD, FTIR results confirm the interaction and complexation between PVDF and (Ag@Se) nanoparticles. In dark and light medium, the antibacterial activity of the produced compositions are evaluated. Additionally, the removal of methylene blue from liquids was detected under visible light. The inhibition zone in visible light of 3(Ag@Se) have the highest values, it was 38 ± 1.6, 41 ± 1.2 mm for Escherichia coli and Staphylococcus aureus, respectively. The removal efficiency rises from 88.8, 89.7, 93.6, to 98.3% upon the Ag@Se contributions after 240 min of continuous irradiation of visible light.
