Abstract
In this study, the electrostatic capacity and dielectric loss tangent for $20{\mu}m$ thick thermal conductivity silicone rubber which is heated at 80 degrees for 8 hours has been measured at temperature of $30^{\circ}C{\sim}170^{\circ}C$, frequency of 0.1~1 MHz. The results of degradation evaluation by this study are as follows. In low frequency, it found that the electrostatic capacity decreased with increasing temperature. On the other hand, it confirmed that the range of the electrostatic capacity narrowed with increasing frequency. It confirmed that there are the carboxylic acid structure and C-O bonding at range of wave number 1,000cm-1 to 1,300cm-1.
