Abstract Research on synthesis of PVDF-SiO 2 nanofiber membrane by electrospinning multi-jet vertical method conveyor collector as a lithium-ion battery separator was systematically investigated. Various voltages 15 kV, 16 and 17 kV types PVDF such Aldrich, Solvay, both mixtures were used for synthesis. The synthesized 4 hours with distance between the tip needle, 10 cm, flow rate 2.6 mL/hour s...

A study on the polyvinylidene fluoride (PVDF) membrane using lignin and lignosulfonate oil palm empty fruit bunch (OPEFB) fillers have been carried out. This aims to determine additional effect of PVDF membrane. Lignin sulfonation has a good result proven by Fourier transform infrared spectra with peak at 1192 cm−1 which indicates sulfonate group. The degree was increased 8.9% for lignosulfonat...

Carbon nanotubes (CNTs) are nanomaterials that have been employed in generating diverse materials. We previously reported that CNTs induce cell death in macrophages, possibly via asbestosis. Therefore, we generated CNT-attached polyvinylidene fluoride (PVDF), which is an established polymer in membrane technology, and then examined whether CNT-attached PVDF is immunologically safe for medical p...

Microporous polyvinylidene fluoride (PVDF) and PVDF nanocomposite membranes were prepared via an isothermal immersion precipitation method using two different antisolvents (ethanol and water). The structure and morphology of the resulting membranes were investigated by wide angle X-ray diffraction (WAXD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and di...

PVDF-based membranes with low-fouling and high permeability properties were developed by blending poly(vinylidene fluoride) (PVDF) poly(2-methoxyethyl acrylate) (PMEA), a polymer, via non-solvent induced phase separation (NIPS). Since PMEA suppresses protein adsorption is insoluble in water, the homopolymer was used as an additive. Consequently, transparent dope solutions containing 15 wt% PVDF...

This study presents an antibody-conjugated polydiacetylene (PDA) and its coated polyvinylidene difluoride (PVDF) membrane. The M149 antibody was hybridized to nano-vesicles consisting of pentacosa-10,12-diynoic acid (PCDA) and dimyristoylphosphatidylcholine (DMPC). After photo-polymerization at 254 nm, the effects on the PDA by antigenic injection were investigated with UV-vis spectroscopy, flu...

A new class of PVDF-based membranes suitable for membrane distillation were prepared via electrospinning. The classical fiber morphology PVDF electrospun was changed to generate a beaded structure by tuning the solvent ratio and operating parameters during fabrication. Results showed that increasing N, N-Dimethylacetamide (DMAC) acetone used prepare solution, micron-sized beads can be created w...

Li-ion battery, separator, multicoreshell structure, thermal stability, long-term stability. A nanofibrous membrane with multiple cores of polyimide (PI) in the shell of polyvinylidene fluoride (PVdF) was prepared using a facile one-pot electrospinning technique with a single nozzle. Unique multicore-shell (MCS) structure of the electrospun composite fibers was obtained, which resulted from ele...

Lithium–sulfur batteries have been considered one of the most promising energy storage in future flexible and wearable electronics. However, shuttling polysulfides, low sulfur utilization, bad cycle stability restricted widespread application lithium–sulfur batteries. Currently, gradient materials with multiple functions can solve those defects simultaneously be applied to various parts Herein,...

In this study, we successfully prepared nine non-woven, supported polyvinylidene fluoride (PVDF) membranes, using a phase inversion precipitation method, starting from a 15 wt % PVDF solution in N-methyl-2-pyrrolidone. Various membrane morphologies were obtained by using (1) PVDF polymers, with diverse molecular weights ranging from 300 to 700 kDa, and (2) different temperature coagulation bath...
