Summary: This study investigates the electrostrictive and structural properties of P(VDF-HFP) nanofibers modified with conductive polymer polyaniline (PANI). The composite nanofibers showed uniform fibers without bead formation, with decreased water contact angle and increased dielectric properties and electromechanical response as the PANI content increased. The results suggest that P(VDF-HFP)/PANI composite nanofibers may offer a promising route for electrostrictive applications in actuation, MEMS, and sensors.

Summary: The effects of thermal processing on the micro- and nanostructural features and relaxor-ferroelectric properties of a P(VDF-TrFE-CFE) terpolymer were investigated. Annealing reduces the Curie transition temperature and shifts the ferroelectric phase fraction, leading to relaxor-ferroelectric behavior. Changes in transition temperatures are related to alterations in hysteresis curves.

Summary: Developing flexible electromagnetic interference (EMI SE) shielding materials is crucial for protecting humans from harmful radiation. We designed and fabricated a flexible multilayer structure of PVDF/GNP-PVDF composite film, which exhibited high EMI SE performance (averaging 69.7 dB in X-band), excellent flexibility, and stability (98.85% retention after bending 1000 cycles at 60 degrees). The theoretical study indicates that the multiple reflection and absorption of electromagnetic waves between layers contribute to the high EMI SE performance of the PVDF/GNP-PVDF multilayer film.

Summary: In this study, a composite film of gamma-phase PVDF with excellent dielectric properties was prepared using a deep eutectic solvent (DES) and montmorillonite (MMT). DES induced the crystallization of gamma-phase and increased the dielectric constant of the composite through increased ion motion. Furthermore, DES promoted the dispersion of MMT layers, inhibiting long-range ion migration and reducing the dielectric loss of the composite. The PVDF/MMT/DES composite films exhibited a high dielectric constant of 32 and a low dielectric loss of 0.06 at 1 kHz. Additionally, the synergistic effect of MMT/DES improved the toughness and optical transmittance of the composite films.

Summary: Inspired by the similarity between rheumatoid arthritis fibroblast-like synoviocytes (RA-FLS) and cancer cells, this study systematically and thoroughly investigates the therapeutic effects of cold air plasma (CAP) on RA. The results demonstrate that CAP with the proper dosage significantly alleviates symptoms and eliminates the root cause by triggering the self-antioxidant capability of the surrounding tissue. The molecular and cellular mechanism reveals that the spontaneous reactive oxygen species (ROS) cascade induces the mitochondrial apoptosis pathway on RA-FLS. This study unveils a new strategy for targeted treatment of RA and provides the theoretical foundation for future development of plasma medicine.

Summary: Silicon (Si) has the potential to replace graphite in next-generation lithium-ion batteries (LIBs) due to its high specific capacity, abundant reserve, and low cost. However, the poor rate performance and short lifespan of Si anodes are still major challenges due to the unstable electrode/electrolyte interface and low ion/electron conductivity. In this study, a mixed ion/electron conducting interlayer (MIECI) consisting of LiF and Li-Mg alloy is formed in situ from an intermediate MgF2 layer to stabilize the electrode/electrolyte interface. The p-Si@MgF2 anode with the MIECI shows excellent cycling stability and superior rate capacity, demonstrating the potential of this interfacial modification and engineering strategy for Si anodes in LIBs.
