TLDR
In this article, the hydrophobicity recovery characteristics of HTV silicone rubber after different corona deterioration time using the static contact angle method were investigated, and the experimental results show that the hydophobicity can get some recovery after the CORONA deterioration, but the procedure of hydrophibicity recovery would be varied with the corona degradation condition, moreover, the hydphobicity would not recover back to the initial value after a certain condition of corona degeneration.Abstract:
This paper has investigated the hydrophobicity recovery characteristics of HTV silicone rubber after different corona deterioration time using the static contact angle method. The experimental results show that the hydrophobicity of HTV silicone rubber can get some recovery after the corona deterioration, and the procedure of hydrophibicity recovery would be varied with the corona deterioration condition, moreover, the hydrophobicity would not recover back to the initial value after a certain condition of corona deterioration, even if the storage time is long enough.read more

Electrical and environmental aging of silicone rubber used in outdoor insulation
TL;DR: In this article, the aging of SIR and hydrophobicity recovery was investigated using both chemical and morphological analysis, and it was shown that oxidation that induces crosslinking, branching, interchanging and a formation of silanol groups are the most dominant chemical reactions during the aging process.

Hydrophobicity loss and recovery of silicone HV insulation
TL;DR: In this paper, the authors reviewed the unique properties of polydimethylsiloxane (PDMS) elastomers that make it suitable for HV applications and suggested that diffusion of low molecular weight PDMS components is the more important mechanism of hydrophobic recovery.
