“…Furthermore, ageing does not increase the stiffness, evidently seen in polypropylene (PP). A German group tested already 2002 PVDF mesh for abdominal wall reconstruction in rats [19]. These results were supported and standardised by our group in in vitro and large animal studies showing good biocompatibility of PVDF [11].…”

h i g h l i g h t sPVDF-mesh is feasible for transvaginal application for cystocele repair. 15% of patients presented any kind of complications and 8.8% needed a resurgery for SUI or POP during the follow-up. Improvement of quality of life was reported by 87.5% according the PGI-I. The preliminary results support the initiation of prospective trial and registry according to IDEAL. a r t i c l e i n f o Results: 34 women were eligible for a mean follow up of 19 months. The functional outcome improved significantly. One symptomatic vault prolapse (2.9%) and two reoperations for incontinence (5.9%) occurred. Two mesh exposures (5.9%) occurred and were treated conservatively. No other severe complications were registered. 87.5% of treated women felt very much better or much better and would undergo the surgery again. A cohort study including development steps in accordance with the IDEAL system is presented. Conclusions: For the first time we report on effectivity and safety of transvaginal application of PVDFmesh in real-life practice. A prospective long-term evaluation in a registry is justified.

“…In particular, fabrication of porous membranes of these materials has attracted interest due to their potential applications as filters; as polymer electrolyte for applications in rechargeable batteries [3,4]; and in biomedical applications [5,6]. Phase separation of the polymer solution for the preparation of porous membranes can be induced by several methods, including immersion precipitation, precipitation from the vapour phase, and thermally induced phase separation (TIPS) [7,8].…”

Ferroelectric macroporous poly(vinylidene fluoride-trifuoroethylene) membranes have been produced by isothermal crystallization from the solution at different temperatures starting from different diluted solutions of the co-polymer in dimethylformamide. In this way pore architecture, consisting in interconnected spherical pores can be obtained.The mechanism and kinetics of solvent evaporation was investigated and related to the evolution of the polymer microstructure. The mechanism underlying the pattern formation has been discussed on the light of the Flory-Huggins (FH) lattice teory, grain 2 boundary effects and the Cahn-Hilliard equation for mass conservation systems. It was also observed that the temperature or initial concentration of the crystallization process does not affect the phase, ferroelectric transition temperature or the melting temperature of the polymer.

“…The increase of molecular weight with the increasing monomer concentration is augmented to a surprise degree, partially due to the reaction pressure. See sc-1 and sc-2 in Table 1, the molecular weight and polydispersity increase from 9.1×10 4 to 40.5×10 4 and from 1.41 to 1.66, respectively, when the initial pressure increase from 10.5 to 26 MPa, although the monomer concentration only increase from 3.13 to 4.38 mol/L. Moreover, see sc-5 and sc-6, the polydispersity also increases from 1.79 to 2.01 when the initial pressure increases from 24.5 to 27.5 MPa.…”

A series of poly(vinylidene fluoride)s (PVDFs) is synthesized in supercritical carbon dioxide (sc-CO 2 ). The influences of polymerization pressure, molecular weight distribution and H-H defect concentration on the crystallization of PVDF have been studied in combination with differential scanning calorimetry (DSC), wide-angle X-ray diffraction (WAXRD) and Fourier transform infrared spectroscopy (FT-IR) measurements. The result shows that the morphology, molecular weights, polydispersity and head-to-head (H-H) defect concentrations of the PVDFs are affected by the reaction pressure and good solubility generated from sc-CO 2. Especially, the sc-CO 2 polymerization has greatly improved the crystallization mode of the obtained PVDFs such as the complete degree of crystallinity, crystallinity and the crystal phase. This will create more comprehensive application fields for PVDF.
