Summary: High-performance PVDF separators have been successfully fabricated for lithium-ion batteries (LIBs) using a crystallization template in PVDF/PBSU blends. The co-continuous structures of crystalline and amorphous phases in PVDF contribute to superior mechanical performance and heat resistance. The removal of PBSU results in the formation of 3D interpenetrated nanochannels, enhancing the diffusion channels and improving the safety of LIBs. The optimal PVDF-30 specimen exhibits higher discharge capacity, higher coulombic efficiency, and enhanced cycle stability compared to the reference material.

Summary: Chitosan-pectin films containing Fe3O4 magnetic nanoparticles were prepared using solution casting method, creating biopolymer-based magnetically active materials. Physical interactions between the matrix and nanoparticles were confirmed by FTIR spectra and DSC results. The structure of the films was influenced by the interactions, leading to changes in mechanical properties. VSM and electrical analysis showed that the films exhibited ferrimagnetic behavior and increased dielectric constant with higher nanoparticle concentration. Additionally, the films demonstrated enhanced antimicrobial activity against both Gram-negative and Gram-positive bacteria. These findings highlight the potential of chitosan-pectin films with Fe3O4 magnetic nanoparticles in active and intelligent food packaging applications.

Summary: PVDF-HFP films incorporating different types of imidazolium ionic liquids with different magnetic anions and imidazolium cation chain lengths have been developed for humidity-sensing applications. The IL/PVDF-HFP composites exhibit a porous structure independently of the IL anion type and cation chain length. The inclusion of ILs induces polymer crystallization into the electroactive beta phase, with the most noticeable increase observed for PVDF-HFP/[Bmim][FeCl4]. The hybrid samples show a decrease in thermal stability and yield strength, with PVDF-HFP/[Bmim]2[Co(SCN)4] samples experiencing the most significant decrease. PVDF-HFP/[Bmim]2[Co-(SCN)4] and PVDF-HFP/[Bmim][FeCl4] composites display the highest magnetization. The PVDF-HFP/[Bmim]2[CoCl4] composite exhibits the highest relative humidity sensing response. The developed IL/polymer composites show potential for humidity sensing applications.

Summary: In this study, Terfenol-D cone-like shaped nanopatterned surfaces were fabricated using sputtering, and their bactericidal effect was enhanced by an alternating magnetic field. Bacterial adhesion analysis showed a reduction of attachment surface on Terfenol-D surfaces compared to control silicon, attributed to material properties and nanostructuration. Therefore, this study presents a method to induce and/or improve the mechanical antimicrobial behavior of surfaces via application of a magnetic field, as an alternative or in combination with chemical methods.

Summary: Solid polymer electrolytes (SPEs) were prepared using an ionic liquid embedded in different fluorinated polymer matrices to evaluate their electrochemical properties and battery performance. The choice of polymer did not significantly affect the morphology and thermal properties of the samples. However, the degree of crystallinity and mechanical characteristics varied with the different polymers. All samples exhibited high ionic conductivity and lithium transference numbers, with the P(VDF-TrFE-CFE) sample showing the highest values. This polymer also demonstrated excellent cycling performance at high discharge rates, making it suitable for lithium-ion battery applications.

Summary: Poly(hydroxybutyrate-co-hidroxyvalerate) (PHBV) is a biodegradable polymer that can be used as a substitute for plastics made from fossil resources. By blending PHBV with poly(caprolactone) (PCL) and poly(lactic acid) (PLA), its properties can be improved, including morphology, wetting, structure, thermal, mechanical, and electrical characteristics. The addition of PCL and PLA also enhances the antibacterial activity of PHBV. This study demonstrates the potential of developing PHBV blends with PCL or PLA for specific applications.
