Study of rheological properties of gel polymer electrolyte

Panda, S (2014) Study of rheological properties of gel polymer electrolyte. MSc thesis.



Two series of samples are prepared to investigate the viscoelastic properties of Gel Polymer Electrolytes. Samples were prepared by gelation technique with different oxygen to sodium ratio. For the present work, we take Poly(vinylidenfluoride) as polymer, sodium perchlorate as salt and of ethylene carbonate and propylene carbonate in the mass ratio of 1:1 and dimethylformamide as solvent for preparing the sample. X-ray diffraction analysis confirms the complexation of polymer with salt. The interplanar spacing and interchain separation of the gel polymer electrolytes were calculated from XRD data. The microstructure the gel polymer electrolytes were analysed with the help of optical microscopy. Viscoelastic properties and thermal stability of the sample were probed using rheological measurements.
