Effects of Seawater and Freshwater Soaking on Chemical and Electrical Condition Monitoring of CSPE

CSPE의 화학·전기적 상태감시에 미치는 해수·담수침지의 영향

The volume electrical resistivity of $3.777{\times}10^{13}{\Omega}{\cdot}cm$ of dried CSPE for 660~750 days after seawater & freshwater soaking is lower than $4.011{\times}10^{13}{\Omega}{\cdot}cm$ of that before seawater soaking. The peak binding energy of oxygen and sulphur of CSPE after seawater & freshwater soaking are shifted above 1.0ev. The grass transition temperature($T_g$) of $-19.76^{\circ}C$ of seawater & freshwater soaked CSPE are lower than $-19.59^{\circ}C$ of that of non-soaked CSPE. The melting temperatures($T_m$) of seawater & freshwater soaked and non-soaked CSPE are $45.58^{\circ}C$ and $45.59^{\circ}C$, respectively.
