| 제목 | Thermodynamics and Morphological Study of PVDF Physical Gels |
| 초록 | From the previous study, PVDF physical gels were found to be formed in various solvents such as propylene carbonate, cyclohexanone and γ-butyrolactone at different conditions. Gelation time was measured by test-tube tilting method (visual method). Gel formation enthalpy was calculated from the gelation rate and polymer concentration. The gelation time was found to be highly dependant on the temperature and concentration in organic solvents, studied. Morphological study of the casting films obtained them cooling slowly at room temperature was also carried out using the SEM(scanning electron microscope) and the results compared among various solvent system. |
