PVDF-bacterialAcetobacter xylinumPolyvinylidene fluoride (PVDF) is a smart material owing to its pyro-, piezo- and ferroelectric properties. For practical application, e.g., as a sensor material however; the non-polar, low-energy, α-phase of PVDF must be transformed into polar β-phase. ...
Beta phase PVDF film formed by casting it into a specially prepared insulating supportThere is disclosed a method for making PVF2 film of beta phase crystalline structure, predominantly. The beta phase is achieved by first exposing a surface of an insulating polymeric support to an A.C. corona...
FTIR spectroscopy along with XRD confirmed the transformation of α to β-phase in the PVDF thin films. The spin coated films exhibited higher β-fraction than that of the pristine PVDF. The β-fraction in the thin films was mainly influenced by the addition of AgNP. The DSC results showed...
Compared to the pure PVDF foam with a low-expansion-ratio of 1.1 times, the PVDF/PMMA (70/30) blend foam showed an expansion ratio as high as 20 times together with a small cell size of approximately 5 mu m. Additionally, the prepared PVDF/PMMA blend foam exhibited a low-thermal ...
This invention, the fluoridation vinylidene resin (PVDF) pressurizing at the film, and the high temperature whose beta phase is new according to the thickness direction of the said film, regards the method in order to remove the pore of the said film. Pressurization and multiplier action of ...
PVDFthin filmgraphenebeta-phasecrystallinityBi-axially oriented electroactive PVDF thin films were prepared by a 3D printing process during which multiple parameters play a critical role in enhancing beta-phase and crystallinity of the thin films. The PVDF molecular chains were rotated and stretched to...
