Composites composed of a polymer matrix and inorganic fillers have attracted tremendous attention owing to their promising application in flexible dielectric film capacitors. However, boosting the energy density while ensuring a high charging-discharging efficiency is still a huge challenge. In this work, Ba0.6Sr0.4TiO3 nanofibers (BST NFs) doped with different contents of ultra-fine Au nanoparticles are precisely prepared by one-step electrospinning, and P(VDF-TrFE-CFE) (PVTC)-based composites incorporated with various nanofibers are further prepared via a solution-casting process. A superior discharged energy density of 14.2 J/cm3 and an excellent energy storage efficiency of 71.3% have been achieved in such monolayer composites by optimizing the doping content and distribution of ultra-fine Au nanoparticles in BST NFs, which are induced by enhanced electric displacement and ensure suppressed energy loss and improved electric breakdown strength. Hence, doping moderate ultra-fine metal nanoparticles in one-dimensional inorganic nanofillers is a feasible strategy for designing polymer-based composites with outstanding performance.

“…Therefore, fluorinated compounds can be used to synthesize dental care materials, especially silver diamine fluoride, quaternary ammonium fluoride salt. Besides, the fluorinated membrane also displayed anti-pollution and anti-wetting properties in the field of industrial wastewater treatment (Abdulkarem et al 2021 ; Cheng et al 2021 ; Ji et al 2021 ; Kang et al 2021 ; Koh and Lee 2021 ; Li et al 2021 ; Nayak and Tripathi 2021 ; Xiao et al 2021 ; Zhong et al 2021 ). Due to this unique performance, the fluorinated membrane can be used to treat wastewater with high salinity and hardness, remove heavy metal ions, separate oil, water, and as a flexible dielectric material and air filter with antibacterial properties.…”

Fluorinated compounds are widely used in the fields of molecular imaging, pharmaceuticals, and materials. Fluorinated natural products in nature are rare, and the introduction of fluorine atoms into organic compound molecules can give these compounds new functions and make them have better performance. Therefore, the synthesis of fluorides has attracted more and more attention from biologists and chemists. Even so, achieving selective fluorination is still a huge challenge under mild conditions. In this review, the research progress of enzymatic synthesis of fluorinated compounds is summarized since 2015, including cytochrome P450 enzymes, aldolases, fluoroacetyl coenzyme A thioesterases, lipases, transaminases, reductive aminases, purine nucleoside phosphorylases, polyketide synthases, fluoroacetate dehalogenases, tyrosine phenol-lyases, glycosidases, fluorinases, and multienzyme system. Of all enzyme-catalyzed synthesis methods, the direct formation of the C-F bond by fluorinase is the most effective and promising method. The structure and catalytic mechanism of fluorinase are introduced to understand fluorobiochemistry. Furthermore, the distribution, applications, and future development trends of fluorinated compounds are also outlined. Hopefully, this review will help researchers to understand the significance of enzymatic methods for the synthesis of fluorinated compounds and find or create excellent fluoride synthase in future research. Key points • Fluorinated compounds are distributed in plants and microorganisms, and are used in imaging, medicine, materials science . • Enzyme catalysis is essential for the synthesis of fluorinated compounds . • The loop structure of fluorinase is the key to forming the C-F bond .

This investigation is motivated by the numerous advantages of electrophoretic deposition (EPD) for the fabrication of polyvinylidene fluoride (PVDF) and composite coatings and the various applications of such coatings. It is demonstrated that gallic acid (GA), caffeic acid (CFA), cholic acid (CA) and 2,3,4 trihydroxybenzoic acid (THB) can be used as charging and dispersing agents for the EPD of PVDF. The deposition yield of PVDF increases in the following order: THB < CFA < CA < GA. Test results indicate that the chemical structure of the dispersants exerts influence on the deposition efficiency. Potentiodynamic and impedance spectroscopy studies show the corrosion protection properties of PVDF coatings. GA is used for the co-EPD of PVDF with nanosilica and micron-size silica. The silica content in the composite coatings is varied by the variation of silica content in the suspensions. The ability to use GA as a charging and dispersing agent for the co-EPD of materials of different types paves the way for the fabrication of advanced organic–inorganic composites using EPD.
