Ultrasonic transducers using PVDF
Ferroelectrics, 1991In a research program on ultrasonic transducers. PVDF has been used for structures needing thinness, flexibility and low acoustic impedance. The specific applications described include focused conical transducers for NDT, array transducers for medical holographic B-scan imaging and transmitters/ receivers for zetapotential measurements in colloidal ...

Evidence for a crystal-amorphous interphase in PVDF and PVDF/PMMA blends
Polymer, 1987Abstract Dielectric relaxation studies and absolute small-angle X-ray investigations give evidence that amorphous interlamellar regions in partially crystalline PVDF/PMMA blends consist of two phases: a pure amorphous PVDF phase and a homogeneously mixed PVDF/PMMA phase. The local phase separation which occurs, despite favourable interactions between

It is very important in modern application of ultrasound to reach the desired sound pressure field in some space. Also we want to measure the field in the same space very precise. Thus, basics properties of elecroacoustic transducers with polyvinilden fluoride (PVDF) are described.

HBPE-g-PVDF/PVDF blend nanofiltration membrane: preparation and characterization
Journal of the Iranian Chemical Society, 2016Hyperbranched polyester-grafted poly(vinylidene fluoride) (HBPE-g-PVDF) was synthesized and used as additive in preparation of PVDF blend membranes. HBPE-g-PVDF copolymer was characterized with FTIR and TGA techniques. The prepared membranes were also characterized with SEM, AFM and contact angle measurement.

Nowadays, mesh repair of abdominal wall hernias has become an integral component of general surgery, even representing the standard procedure in various countries. Currently used mesh prosthesis are made of polypropylene (PP), poly-ethylene-terephtalate (PET) or polytetrafluorethylene (PTFE), though all of them reveal some disadvantages. Therefore, the
