실리콘고무의 유전율과 유전손실에 관한 연구 = A Study on the dielectric constant and dielectric loss factor of silicone rubber

다국어 초록 (Multilingual Abstract)

The characteristics of the dielectric relaxation in silicone rubbers were studied in the frequency range of 1×10²∼??[Hz] at the temperture range of 30[℃]∼170[℃].
As the results of the study, it has been confirmed that the silicone rubber containing the cross-linking agents of 2.5-bis(tert-butylperoxy)-2.5-dimethyl haxane exhibit the dissipation spectra of two kind[α, βdissipation] due to the siloxane and methyl groups. Particularly, the maximum value of dietectric loss spectra of silicone rubber combing the closs-linking agents of 0.7[phr] to 1.0[phr] are on the increasing in high frequency region, but the specimen of above 1.0[phr] become smaller again.
The energy and the entropy of activation on the molicular motion obtained 18.32[cal/mole] and 1.48[cal/mole.deg] in measuring condition respectively.
