Study on the Improvement of Hydrophobicity of PVDF Films
(5-12)  Journal of Thermoplastic Composite Materials 24 #1 (2011)
Abstract
Huang and Chen of the Industrial Technology Research Institute and National Central University, Taiwan, found that the surface properties of poly(vinylidene fluoride) (PVDF) films containing  polyethylene glycol (PEG) films varied with the concentration of PEG.  The hydrophobicity of PVDF films was improved by changing the morphology of the surface of the films.  (RDC 2/24/2011)

The Role of Solvent Evaporation in the Microstructure of Electroactive β-Poly(Vinylidene Fluoride) Membranes Obtained by Isothermal Crystallization
(1 – 14) Soft Materials 9, #1 (2011).
Magalhães et al of Portugal and Spain obtained electroactive β-poly(vinylidene fluoride) (PVDF) membranes by isothermal crystallization from solution.  Different morphologies and microstructures were obtained by crystallizing at different temperatures. The solvent evaporation is ruled by two steps, related with a metastable- unstable-metastable transition in the solution phase diagram. Scanning electron microscopy revealed the porous structure and the variations of the morphology with the variation of the isothermal evaporation temperature. Finally, the infrared spectroscopy measurements confirm that the polymer crystallizes in the electroactiveβ-phase of PVDF. (RDC 2/9/2011)
