TLDR
In this paper, the authors presented the results of a study on the hydrophobicity loss of HTV silicone rubber under different corona discharge conditions, and the experimental results showed that the speed and grade of hydrophobia loss vary with the corona's discharge time and corona intensity.Abstract:
This paper presented the results of a study on the hydrophobicity loss of HTV silicone rubber under the different corona discharge conditions. The experimental results show that the speed and grade of hydrophobicity loss vary with the corona discharge time and the corona intensity. Moreover, it is noticed that the hydrophobicity would not become worse as long as the corona intensity keeps below a certain level.read more

On the aging of oxygen plasma-treated polydimethylsiloxane surfaces
TL;DR: Oxygen plasma-treated polydimethylsiloxane surfaces were aged in a low energy (air) and in a high energy (water) medium, and the results showed that when aging was performed in water, a high surface tension was maintained as discussed by the authors.

Impact of corona on the long-term performance of nonceramic insulators
TL;DR: In this article, two sources of corona have been investigated: corona from a metal electrode, and Corona from water droplets, and the results show that corona induced degradation is dominantly due to a combination of electro-chemical reactions rather than thermal effects.
