Study of a composite solid electrolyte made from a new pyrrolidone-containing polymer and LLZTO
2020, Journal of Colloid and Interface ScienceCitation Excerpt :PPO) are shown in Schemes 1 and 2, respectively. In the design, the ethylene oxide (EO) moieties on the side chain are used mainly for the conduction of lithium ions in the classic mode, and at the same time, N-vinyl-2-pyrrolidone (NVP) moieties are introduced not only to assist in lithium ion transportation, but also to adjust the glass transition temperature (Tg) and to see if its weak coordinating ability [66-68] enhances the combination with LLZTO nanoparticles, a key point in this research. Li6.40La3Zr1.40Ta0.60O12 (LLZTO) was obtained from Tai'an Faraday Energy Technology Co., Ltd.
Loading of Cefixime to pH sensitive chitosan based hydrogel and investigation of controlled release kinetics
2020, International Journal of Biological MacromoleculesCitation Excerpt :Amide-V (-CH2 rocking) absorbs at 732 cm−1 was observed [29]. All the hydrogels have same kind of absorption peaks with difference in intensity based on crosslinking by inter molecular hydrogen bonding [30,31]. TGA involves the measurement of weight loss as a function of temperature and TGA responses observed are shown in Table 1 for TAP 4, TAP 8, TAP 16 and TAP 32 formulations.
PVA/PVP blend polymer matrix for hosting carriers in facilitated transport membranes: Synergistic enhancement of CO<inf>2</inf> separation performance
2020, Green Energy and EnvironmentCitation Excerpt :Although PVP is more hydrophilic than both PVA and the 50/50 PVA/PVP blend while PVA has the best membrane coating, the blend membrane of PVA/PVP (50/50) has the highest CO2 permeance among the tested membranes, demonstrating the synergetic enhancement of the two polymers in the blend membrane. It is also observed that the addition of PVP could reduce the crystallinity of PVA, as suggested by Zhang et al. [41], where the crystalline phase of PVA disappeared at a PVA level below 46% in a PVA/PVP blend. The reduced crystallinity is beneficial for a relatively higher CO2 permeance.
Development of a novel type of solid polymer electrolyte for solid state lithium battery applications based on lithium enriched poly (ethylene oxide) (PEO)/poly (vinyl pyrrolidone) (PVP) blend polymer
2017, Electrochimica ActaCitation Excerpt :Presence of the rigid pyrrolidone group in amorphous PVP helps to provide better ionic mobility in these systems. The carbonyl group (CO) attached to the side chains of PVP helps in the formation of a number of complexes with different inorganic salts [21–24]. Doping with lithium salts is another important criterion to realise the final application of SPE films in Li-ion cells.
Blend miscibility of cellulose propionate with poly(N-vinyl pyrrolidone-co-methyl methacrylate)
2013, Carbohydrate PolymersStudy on the phase separation of plasticised starch/poly(vinyl alcohol) blends
2012, Polymer Degradation and StabilityCitation Excerpt :13C CP/MAS spectra of PlS/PVOH blends (50:50, 75:25, 90:10) and their pure components (0:100 and 100:0) are displayed in Fig. 7. Changes in chemical shifts and/or in line shapes have previously been observed in the 13C NMR spectra of blends such as in cellulose or PVOH blends in comparison with the spectra of the unblended components [38–40]. Changes in chemical shifts can be related to the incidence of hydrogen bonding, since this type of interaction strongly influences the electron density around the carbons bearing the interacting functionalities.
