| Research Abstract |
poly(vinylidene fluoride)/propylene carbonate (PVDF/PC) solution forms physical gels by cooling. This type of gel is used such as binder for polymer gel electrolyte of lithium ion battery. However, fundamental understanding on gelation behavior and gelation condition to improve the physical properties has not been well studied. Therefore, firstly, we conducted the light scattering and optical microscope measurements and revealed that PVDF/PC solution formed the spherical domain driven by nucleation and growth type phase separation. Secondly, we carried out the deformation experiments and found that the mechanical properties were improved as the gelation temperature increased.
