Article Abstract

Water-processable hybrid piezo- and thermo-electric materials have an increasing range of applications. We use the nanoconfinement effect of ferroelectric discrete molecular complex [Cu(l-phe)(bpy)(HO)]PF·HO () in a nonpolar polymer 1D-nanofiber to envision the high-performance flexible hybrid piezo- and thermo-electric nanogenerator (TEG). The 1D-nanoconfined crystallization of enhances piezoelectric throughput with a high degree of mechano-sensitivity, i.e., 710 mV/N up to 3 N of applied force with 10,000 cycles of unaffected mechanical endurance. Thermoelectric properties analysis shows a noticeable improvement in Seebeck coefficient (∼4 fold) and power factor (∼6 fold) as compared to its film counterpart, which is attributed to the enhanced density of states near the Fermi edges as evidenced by ultraviolet photoelectric spectroscopy and density functional based theoretical calculations. We report an aqueous processable hybrid TEG that provides an impressive magnitude of Seebeck coefficient (∼793 μV/K) and power factor (∼35 mWmK) in comparison to a similar class of materials.

The 'pyro-phototronic effect' plays a nontrivial role in advancing ferroelectric (FE) devices of light detectors, light-emitting diodes, and other smart technologies. In this work, a premier FE copolymer, poly(vinylidene fluoride--trifluoro ethylene) (P(VDF-TrFE)), is reinforced with a lead-free double perovskite, CsSnI, to render profound properties in a hybrid nanostructure. It presents a unique example of the coupling of ferro-, pyro- and piezo-electrics to the 'photoexcitation' of exotic charges that actively empower the synergetic features.

Coupling piezo-active and triboelectric materials has recently emerged as an effective technique for developing high-performance hybrid nanogenerators (HNGs). This is the first paper to report the fabrication of piezo-active poly(vinylidene fluoride-hexafluoropropylene)(PVDF-HFP)/MXene-based hybrid composite fibers through conventional electrospinning. Here, the effect of MXene content (1-5%) on the surface potential and electrical performance of the as-synthesized composites is investigated and optimized.

Solar-driven HO-to-H conversion is a feasible artificial photoconversion technology for clean energy production. However, low photon utilization efficiency has become a major obstacle limiting the practical application of this technology. Herein, a metal atomic replacement (Sb→Ni) is conducted to disintegrate bulk SbS nanorods and synchronously grow the NiS nanolayers, and a flower-like SbS-NiS nanocomposite with high BET specific surface area and synergistic exciton dynamics is constructed for simulated solar (SSL)-driven HO-to-H conversion.

This study investigates the influence of flexoelectricity on the coupled electromechanical behavior of MXene/graphene-based hybrid piezocomposite (MGHPC) plates. We developed an analytical model based on Navier's solution and Kirchhoff's plate theory, as well as an approximate model based on the Ritz method for validation purposes. A three-phase micromechanical modeling is developed for determining the effective properties of MGHPC composed of 2D MXene and graphene nano-reinforcements embedded in an epoxy matrix.
