| Outline of Final Research Achievements |
We proposed new method to characterize or check the wettability using the non-contact surface resistivity tester. The tester measured normalized surface potential, a measured surface potential divided by an applied surface potential due to corona discharger. The relationship between the contact angle and the normalized surface potential is measured for variously deteriorated silicon rubber samples prepared by a commercial corona treatment equipment. The results showed that the normalized surface potential was increased with decreasing contact angle and with increasing humidity. The wettability could be a function of the surface resistivity depending on the amount of deposited water vapor on the surface.
