“…Under high loading, the Lichtenecker logarithmic law overpredicts those measured values. Such derivation probably is induced by the insufficient macromolecular chains left to shelter the nanofillers and thus the increase of porosity in the nanocomposite [40]. The surface‐modified BaTiO 3 nanoparticles with TDPA yielded well‐dispersed and high‐quality nanocomposite thick film in the PVDF host, which provides fundamental structure for improvement of dielectric property.…”

It's significantly urgent to develop the polymer film capacitor with large energy density and high charge-discharge efficiency for the applications of portable electronics and power hybrid system. In this study, poly(vinylidene fluoride) (PVDF) nanocomposite film incorporated with tetradecylphosphonic acid modified BaTiO 3 was prepared via solution casting to achieve high dielectric property and large energy density. The strong interactions were formed between modifier and polymer segments, which was characterised by X-ray absorption near edge structure of synchrotron radiation. The decrease of activation energy indicates that the functionalisation of BaTiO 3 weakens the heterogeneous nucleation of nanoparticle. The dielectric constant of 30 vol.% nanocomposite film achieves 50.1 with low loss of 0.02 at 100 Hz, which is attributed to the strong interaction between the phosphonic acid and fluoride atoms of PVDF segments. The energy density of 20 vol.% nanocomposite is 4.4 J/cm 3 with charge-discharge efficiency of 78% at 120 MV/m due to the large interfacial polarisation. The functionalisation strategy of high-k nanofillers enhances the compatibility in polymer nanocomposite, which contributes to the flexible polymer capacitor with large energy density and high charge-discharge efficiency.

“…However, the peak at 5.156 keV is specific to Ba with no counterpart in Ti. [35,36] Increasing BT content from 1 to 5 wt% intensified the Ti characteristic peaks, which shows that 90/10/5 and 70/30/5 have higher amounts of BT nanoparticles than those of 90/10/1 and 70/30/1 nanocomposites. Taking into account Figure 3A,B, 90/10/1 yields higher peaks of F than those of 70/30/1 which confirms higher content of PVDF in the composites.…”

Polyamide 6 (PA6) as a cost‐effective polar polymer and barium titanate (BT) as piezoelectric ceramic nanofiller were melt compounded with poly(vinylidene fluoride) (PVDF) matrix to enhance the β electroactive phase. A series of samples with two blending ratios of PVDF/PA6 (90/10 and 70/30 [wt%/wt%]) each containing 1, 3, and 5 wt% of BT were prepared. The SEM results revealed that the addition of BT to the neat blends refined the biphasic morphology which is mainly due to selective localization of BTs in PA6 dispersed phase as confirmed by TEM observation and wetting parameter predictions. The EDX analysis demonstrated a uniform distribution of BT nanoparticles in the filled systems. FTIR and XRD results showed that β content increased as a result of blending while the α phase was suppressed. The BT nanoparticles inclusion to the blends showed a synergistic effect on the β‐polymorph content. These results in combination with the data derived from DSC (indicating reduction of the total crystallinity) complement the idea of β enhancement by the addition of BT nanoparticles and PA6 into PVDF.

“…Hunpratub et al [ 74 ] believe that BCTZO (Ba 0.85 Ca 0.15 Ti 0.9 Zr 0.1 O 3 ) particle is an alternative material as function phase and revealed the effect of particle size on dielectric and piezoelectric properties. Additionally, BNBT (0.94(Bi 0.5 Na 0.5 )TiO 3 -0.06BaTiO 3 ) [ 75 ] and BNBK (0.88Bi 0.5 Na 0.5 TiO 3 -0.08Bi 0.5 K 0.5 TiO 3 -0.04BaTiO 3 ) [ 76 ] have been used as a function phase to fabricate the composite. Although lead-free piezoelectric materials are potential functional materials, the lower piezoelectric properties and poor temperature stability still limit their application in CPCs.…”

Compatibility, a critical issue between sensing material and host structure, significantly influences the detecting performance (e.g., sensitive, signal-to-noise ratio) of the embedded sensor. To address this issue in concrete-based infrastructural health monitoring, cement-based piezoelectric composites (piezoelectric ceramic particles as a function phase and cementitious materials as a matrix) have attracted continuous attention in the past two decades, dramatically exhibiting superior durability, sensitivity, and compatibility. This review paper performs a synthetical overview of recent advances in theoretical analysis, characterization and simulation, materials selection, the fabrication process, and application of the cement-based piezoelectric composites. The critical issues of each part are also presented. The influencing factors of the materials and fabrication process on the final performance of composites are further discussed. Meanwhile, the application of the composite as a sensing element for various monitoring techniques is summarized. Further study on the experiment and simulation, materials, fabrication technique, and application are also pointed out purposefully.
