Polymer composites of P(VDF-TrFE) and Tri(hydroxymethyl) nitromethane as filler material with different concentrations have been prepared. Tris(hydroxymethyl) is an organic ferroelectric low preparation cost easy processing, it also lightweight. Its properties enable to be a potential candidate for use in polymers improve their ferroelectric, dielectric, piezoelectric properties. We investigated the effect content on dielectric polymer. Our results show that retains its crystallinity after embedding polymer matrix. It does not alter crystalline β-phase All possess higher polarization compared pure P(VDF-TrFE). Up 11.4 µC/cm2 remnant constant 14 at 1000 Hz obtained free-standing 10 wt% composite film.

Paraelectric-ferroelectric phase transitions have been mainly acknowledged by the order-disorder type in most molecular ferroelectrics or displacive inorganic ferroelectrics. However, reports regarding symmetry-breaking ferroelectric induced distortion coordination geometry scarce. In this study, we present a lithium complex [Li(1,10-phenanthroline)2]I, which undergoes an Aizu mmmFmm2 transition at 371 K. Its ferroelectricity has identified geometric of ions environment and concomitant directional movement iodide ions. Besides, loop [Li(1,10-phenanthroline)2]I can be readily obtained from polarized polycrystalline pellet room temperature; addition, its nonlinear optical signal is comparable to that KH2PO4 (KDP). To best our knowledge, represents first lithium-based organic exhibiting geometry-triggered transition. This work will provide significant inspiration for design novel

Organic–inorganic metal halides (OIMHs) have attracted great interest in the design of various functional materials due to their advantages easy processability, rich structural diversity, and assembly flexibility. However, rational control stacking patterns OIMHs for regulation has been a long-standing challenge. Particularly, little is known about intrinsic relationship between dimensions dielectric response at molecular scale. Here, we investigated modulation effect cationic halogen engineering (N,N-dimethylethanolamine)PbBr3 on stacking, as well its impact thermal, electrical, optical physical properties. Halogen brings varied from one-dimensional (1D) hexagonal perovskite structure two-dimensional (2D) layered an interlocking 1D chain structure. These attributes demonstrated be closely related interactions crystal lattice, leading variation sequential increase phase transition temperature differences response, with similar bandgaps that are mainly determined by inorganic frameworks. This study offers new insights into performance optimization organic–inorganic hybrids.
