1999年4月1日 · XPS spectra of graphite-filled poly(vinylidene fluoride) (PVdF) are presented. The specimen consists of 17 wt % PVdF and 83 wt % graphite. A freshly cut surface was examined …

F1s spectra show a change in the ratio of covalent and semi-ionic bonds. Although the change is not enormous, semi-ionic bonds are more prevalent in pure PVDF material (Figure 7 a) than in …

In this work, we modulated the content of BaTiO3/multi-wall carbon nanotubes (MWCNTs) in the BaTiO3/MWCNTs/PVDF electrospun nanofibers to facilitate the β phase formation in the …

We report switching behavior between the ferroelectric β phase and the paraelectric α phase in polyvinylidene fluoride–multiwalled carbon nanotube (PVDF–CNT) nanocomposite. The …

2000年4月1日 · Location of PMMA at the PC/PVDF interface has been confirmed by XPS analysis, which shows that the interface enrichment in PMMA already takes place when only …

2006年9月7日 · The characterization was accomplished using X-ray photoelectron spectroscopy (XPS) as a primary tool. The results indicate that the piezoelectricity of PVDF thin films and …

The polymorphs of PVDF and its copolymers are typically identified using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC). …

The XPS integral intensity of the F1s line and its satellite is measured during the long-term radiative carbonization of PVDF (polyvinylidene fluoride). A model is proposed that describes …

2019年10月31日 · We report switching behavior between the ferroelectric β phase and the paraelectric α phase in polyvinylidene fluoride–multiwalled carbon nanotube (PVDF–CNT) …

Example #1 (A, B): XPS analysis of the PVDF surface modification. C 1s signal reveals two typical PVDF peaks, PVDF (1) and PVDF (2), together with hydrocarbon and C-OH contamination. …
