Jan 11, 2024 · NMP (N-Methyl-2-pyrrolidon) is primarily used as the solvent for PVDF. Due to its high chemical resistance, NMP is often recycled and can be reused after a drying process.

Dec 21, 2016 · FT-IR (Fourier transform infrared spectroscopy) spectra of PVDF (poly(vinylidene fluoride)) film prepared using NMP (N-methyl pyrrolidone) as a solvent at a 40 °C evaporation temperature.

In this paper, the effect of the crystalline microstructures of polyvinylidene fluoride (PVDF), as cathode binder, on mechanical and electrochemical properties of the cathode, and on the cell...

The state-of-the-art manufg. process of making lithium ion batteries (LIBs) uses a toxic org. and petroleum-derived solvent, N-methylprrolidone (NMP), to dissolve polyvinylidene fluoride (PVDF) to form a slurry consisting of active materials and conductive agents.

SEM images of the surfaces and cross-sections of PVDF membranes prepared with nonsolvent-induced phase separation, with HMPA, NMP, DMAc or TEP used as the solvent to dissolve PVDF. XRD and FTIR/ATR analyses were performed to examine the crystalline phases at the membrane surfaces.

3 days ago · Additionally, FT-IR analysis is conducted on different molar ratios of LN (Fig. S2 a). As the NMP content decreases, the size of the band corresponding to O=C-N significantly diminishes and shifts towards a higher frequency. When x in LN-x is ≤ 5, the size and position of the band remain relatively stable. ... PVDF-HFP-LiTFSI-DMSO-NMP (P[LDN ...

Aug 11, 2021 · This work investigates how thermal treatment conditions of PVDF/NMP/[EMIM][TFSI] electrolyte affect its surface morphology, phase composition and chemical composition. The ionic liquid, polymer matrix and solvent were mixed in …

Jul 6, 2016 · In this study, we developed a simple method for preparing PVDF films using antisolvent addition and controlling their crystalline structure.

2 days ago · PVDF-HFP (160 mg) is dissolved in 120 mg of NMP (anhydrous, 99.5%) using a glass vial (Fisher Scientific, 6 Dram vials, class B borosilicate glass) and a magnetic stir bar (VWR) on a stir plate ...

2 days ago · Figure 2b displays the FT-IR spectra of the CNM/PAC/PVDF membranes before and after chemical modification by the dip-coating method with 1–2 wt.% PFTES for 24 h. As can be seen from that figure, the chemically modified membrane showed a peak at 1148 cm −1 , which indicated a successfully coated membrane surface with silane solution and Si-O ...
