Abstract

A needle-plane electrode system was used to study the characteristics of the silicone rubber under AC corona. Microstructure and chemical structure change analysis on the surface of silicone rubber after corona ageing was made by using SEM, AFM and FTIR. Infrared spectrum shows that corona would cause the rupture of fundamental chain and branched chain of material. Along with the increase of corona aging time, the content of fundamental chain and branched chain will decrease. The continuous increase in the content of carbanyl group shows the intensifying oxidation. Hydroxyl -OH turns into combined condition from dissociative condition.
