“…In this study, PVP could remain dissolved state in solution due to its high solubility. PVP has a broad endothermal peak around 50–100 °C [ 40 , 41 , 42 ], which is not observed in DSC curves of any cocrystal screening products. Besides, the PXRD spectrum of PVP, shown in Figure 9 , has broad peaks around 11° and 20° corresponding to the PVP crystalline phase, although PVP has a poor crystallinity degree.…”

In this study, we attempted to prepare carbamazepine (CBZ) cocrystal through the solution method in ethanol-water solvent mixture (volume ratio 1:1) and polyvinyl pyrrolidone (PVP) solution. Nicotinamide (NIC) and saccharin (SAC) were selected as cocrystal coformers. Cocrystal screening products were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), and Powder X-ray Diffraction (PXRD) techniques. Characterization results show that in ethanol-water solvent mixture, pure CBZ-NIC cocrystal can be prepared, while CBZ-SAC cocrystal cannot be obtained. The addition of PVP can inhibit CBZ-NIC cocrystal formation and facilitate CBZ-SAC cocrystal formation.

Abstract.A new thin film sodium ion conducting plasticized polymer electrolyte based on poly(vinyl pyrrolidone) (PVP) complexed with NaC103 salt systems was prepared by the solutioncast method. The interaction of NaC103 salt with PVP was confirmed by Infrared (IR) study. Charge transport of these polymer electrolytes is due to ions, which was confirmed by Wagner's polarization method. From the conductivity measurements, the highest conductivity value 6.71 x 10 -5 S/cm was observed for the composition PVP:PEG:NaC103(30:60:10) at room temperature 35 ~ The redox behaviour and good reversibility of the plasiticized electrolytes are confirmed by electrochemical techniques. Electrochemical ceil studies of these polymer electrolytes were analyzed from their discharge characteristics. The open-circuit voltage (OCV) and short-circuit current (SCC) were tbund to in the range of 2.52 V to 2.36 V and 760 gA to 1040 gA, respectively.
