“…The differential scanning calorimetry (DSC) studies were performed under nitrogen atmosphere using Mettler ® Toledo DSC 822 e with heating and cooling rate 10 C min À1 . The degree of crystallinity was determined as the ratio between ΔH m and ΔH 0 m , as Equation (2).…”

“…These increases can be attributed to the easier orientation of the PVDF-HFP dipoles, favoring crystallization with relating smaller spherulites as shown in Figure 7c,d. 31 Furthermore, the melting enthalpies (ΔH m ) can be calculated from DSC thermography, and then, the degree of crystallinity (X c ) of the samples may be obtained using Equation (2). Thus, the HImMg content increased, the crystallinity of PVDF-HFP gradually increased due to the nucleating effect.…”

“…Metal–organic framework (MOF) composites/hybrids, which are structures composed of one MOF plus one or more other constituent materials with properties significantly different from those of the individual components, have grown in popularity recently. An MOF is a crystalline material composed of metal ions linked together by an organic linker 1–4 . The advantage of both MOFs (structural adaptivity and flexibility) and various types of functional polymers (thermal, chemical, softness stability, and unique optical, electrical, and magnetic properties) can be combined effectively in MOF/polymer composites in various applications, such as energy, environmental, biomedical, and sensing applications 5–9 .…”

The effects of processing techniques significantly alter on the electroactive β-phase, thermal, and dielectric behavior of polymer composites. The metalorganic framework filler (C 3 N 2 H 5 )(Mg(HCOO) 3 ), HImMg is prepared and introduced into poly(vinylidenefluoride-co-hexafluoropropylene) (PVDF-HFP) matrix using two distinguished methods: melt-mixing and solution-casting methods. The processing conditions are important in determining the dominant phase in PVDF-HFP. As a result of solvent-induced crystallization, the β-phase content of solution-cast composites containing 10% HImMg is 22% higher than that of melt-mixed composites. In both methods, the nucleating effect of HImMg particles increases the overall crystallinity of the polymer matrix and enhances the dielectric constant in composite films by improving the interfacial and dipolar polarization. Furthermore, the melt-mixed composites with 7 wt% HImMg demonstrate the highest dielectric constant of 17.8 at 1 kHz, showing an enhancement of 59% compared with that of pristine PVDF-HFP. Meanwhile, the dielectric loss is suppressed at 0.083. These findings suggest the possibility of enhancing composites' electroactive phase and dielectric properties without mechanical stretching or a large electrical field.

As one type of promising inorganic–organic hybrid crystal material, metal‐organic frameworks (MOFs) have attracted widespread attention in many potential fields, particularly in energy storage and conversion. Recently, effective strategies have been developed to construct uniform nanoscale MOFs (NMOFs), which not only retain inherent advantages of MOFs but also develop some improved superiorities, including shorter diffusion pathway for guest transportation and more accessible active sites for surface adsorption and reaction. Additonally, their nanometer size provides more opportunity for post‐functionalization and hybridization. In this review, recent progress on the preparation of NMOFs is summarized, primarily through bottom‐up strategies including reaction parameter‐ and coordination‐assisted synthesis, and top‐down strategies such as liquid exfoliation and salt‐template confinement. Additionally, recent applications of NMOFs in batteries as electrodes, separators, and electrolytes is discussed. Finally, some important issues concerning the fabrication and application are emphasized, which should be paid attention in future.
