Hydrophobic, chemically resistant nanofiltration (NF) polymeric membranes could provide major improvements to a wide range of processes, from pharmaceutical manufacturing hazardous waste treatment. Here, we report the fabrication first poly (vinylidene fluoride) (PVDF) NF retaining their hydrophobicity and surface chemistry. This was achieved by incorporating in polymer 2D siloxene, which induc...

A highly flexible free-standing Zn anode for ZIBs is fabricated from commercial paste, carbon nanotubes, and poly(vinylidene fluoride)-co-hexafluoropropylene via spin coating. with showed improved rate performances.

Mineralization of poly(vinylidene fluoride) (PVDF), fluoride-co-hexafluoropropylene) [poly(VDF-co-HFP)] copolymer, and poly(ethylene-co-tetrafluoroethylene) copolymer (ETFE) in superheated water the presence an alkaline reagent was investigated with aim developing a technique to recycle fluorine element. These polymers underwent almost complete defluorination form fluoride ions (F–) reaction so...

Vinylidene fluoride [VDF] oligomer is a novel substance with a smaller number of VDF units and lower molecular weight than poly(vinylidene fluoride) [PVDF]. We previously reported that the piezoelectric coefficient of VDF oligomer was greater than that of vinylidene fluoride/trifluoroethylene copolymer [P(VDF/TrFE)], and that a film composed of VDF oligomer was thin and uniform. However, the pi...

The discovery of the piezoelectric properties of poly(vinylidene fluoride) (PVDF) by Kawai [Kawai, 1969], and the study of its pyroelectric and nonlinear optical properties [Bergman et al., 1971; Glass, 1971] led to the discovery of its ferroelectric properties in the early 1970s. Since that time, considerable development and progress have been made on both materials and devices based on PVDF. ...
