Effect of non-solvent additives on the structure and performance of PVDF hollow fiber membrane contactor for CO2 stripping [PDF]

, 2012
Microporous polyvinylidene fluoride (PVDF) hollow fiber membranes with various non-solvent additives, i.e. lithium chloride, glycerol, polyethylene glycol (PEG-400), methanol and phosphoric acid, were fabricated for CO2 stripping via membrane contactors.

Polyvinylidene fluoride (PVDF) Nanofiber Modified Current Collector in Anode-Free Lithium Battery

Indonesian Journal of Applied Physics
In order to coat the layer of the Cu for an anode-free lithium battery (AFLB) and examine AFLB performance, PVDF nanofiber with electrospinning is used. The fabrication time and molecular weight of the nanofiber can be modified.

Towards permanent hydrophilic PVDF membranes. Amphiphilic PVDF-b-PEG-b-PVDF triblock copolymer as membrane additive

European Polymer Journal, 2020
Poly(vinylidene fluoride) (PVDF) ultrafiltration membranes were prepared by non-solvent-induced phase separation (NIPS) using a blend of a new amphiphilic PVDF-based triblock copolymer (PVDF-b-PEG-b-PVDF) and high molar mass PVDF. During the phase inversion step, the triblock copolymer acts both as a pore forming and surface modifying agent.

Preparation and Characterization of PVDF/Alkali-Treated PVDF Blend Membranes [PDF]

Advanced Materials Research, 2012
Poly(vinylidene fluoride) (PVDF) powder was treated with aqueous sodium hydroxide to obtain partially defluorinated fluoropolymers with expected properties such as improved hydrophilicity and fouling resistance (used as membrane material). The effects of concentration of aqueous sodium hydroxide were investigated. The results showed that the membrane’s

First-principles simulations of PVDF copolymers with high dielectric energy density: PVDF-HFP and PVDF-BTFE

Physical Review B, 2016
Phase diagrams of polyvinylidene fluoride (PVDF) and its copolymers with hexafluoropropylene (HFP) and bromotrifluoroethylene (BTFE) are investigated via first-principles simulations and compared to previously studied P(VDF-chlorotrifluoroethylene) (CTFE) data.

E-beam irradiation of poly(vinylidene fluoride-trifluoroethylene) induces high dielectric constant and all-trans conformation for highly ionic conductive solid-state electrolytes

Energy Materials and Devices, 2023
Polymer matrices have limited abilities to dissociate lithium salts and transport ions, thus making most solid-state polymer electrolytes (SPEs) have extremely low ionic conductivities (10−7–10−5 S/cm) at 25 ℃.
