Effect of neutron irradiation on poly (vinylidene difluoride) - Lithium BIS (Oxalato) borate solid polymer film / Nurul ‘Adillah Heffny

Poly (vinylidene difluoride)-lithium bis (oxalato) borate (PVDF-LiBOB) solid polymer films were prepared with different LiBOB salt compositions of 9, 20, 30, 40 wt % by solution casting method. The X-ray diffraction (XRD) studies reveals that the sample with 40 wt% LiBOB is the most amorphous. By de...
