Development of polar phases in ferroelectric poly(vinylidene fluoride) (PVDF) nanoparticles
نویسندگان
چکیده
Ferroelectric polymer nanoparticles of poly(vinylidene fluoride) (PVDF) were prepared by dialysis nanoprecipitation. Particles with mean diameter 230 nm show piezoelectric response as observed Piezoresponse Force Microscopy (PFM). The origin this ferroelectric behavior has been attributed to the presence ferroelectrically active crystalline phases PVDF in (mainly ? and ? phases) demonstrated differential scanning calorimetry (DSC) temperature dependent Fourier transform infrared spectroscopy (FTIR) X ray diffraction. combination preparation method treatment can provide a for tuning ferroelectricity homopolymer nanoparticles.

Preparation of Polyvinylidene Fluoride (PVDF) Hollow Fiber Hemodialysis Membranes
In this study, the polyvinylidene fluoride (PVDF) hollow fiber hemodialysis membranes were prepared by non-solvent induced phase separation (NIPS). The influences of PVDF membrane thickness and polyethylene glycol (PEG) content on membrane morphologies, pore size, mechanical and permeable performance were investigated. It was found that membrane thickness and PEG content affected both the struc...

We report the cases of two patients diagnosed with Morgagni hernia who presented with nonspecific abdominal symptoms. Both underwent laparoscopic surgery that used a dual-sided mesh, polyvinylidene fluoride (PVDF; Dynamesh IPOM®). The procedures were successful and both patients were discharged with no complications. There was no recurrence in 18 months of follow up.Herein is the report of thes...
متن کاملEfficient Immobilised TiO2 in Polyvinylidene fluoride (PVDF) Membrane for Photocatalytic Degradation of Methylene Blue
Immobilised titanium dioxide (TiO2) in membrane structures has recently become attractive. This is due to the elimination of the separation step after the process of photocatalytic degradation. The efficiency of the TiO2 surface area exposed to UV light as the main important parameter needs to be considered. The immobilisation of TiO2 nanoparticles in the polyvinylidene fluoride (PVDF) membrane...

متن کاملPositive temperature coefficient of magnetic anisotropy in polyvinylidene fluoride (PVDF)-based magnetic composites
The magnetic anisotropy is decreased with increasing temperature in normal magnetic materials, which is harmful to the thermal stability of magnetic devices. Here, we report the realization of positive temperature coefficient of magnetic anisotropy in a novel composite combining β-phase polyvinylidene fluoride (PVDF) with magnetostrictive materials (magnetostrictive film/PVDF bilayer structure)...
