The addition of PDMS rubber (30%) to the virgin EOC1 causes the reduction in the crystallite size and degree of crystallinity of EOC from 5.
On the other hand, for the virgin EOC2, the reduction in the overall crystallinity is small as compared with EOC1 upon irradiation.
Figure 7 depicts the dielectric constant ([epsilon]') and dielectric loss ([epsilon]") of irradiated and non-irradiated 70:30 EOC1 PDMS and 70:30 EOC2 PDMS blends.
