Abstract

The recovery of hydrophobicity of nylon insulators after aging by long exposure to a stress of saline water at different temperatures is investigated. The hydrophobicity is determined by measuring the contact angle of a droplet of distilled water on nylon. The aging of nylon was performed by immersing it for up to 336 h in saline water solutions in the range 5.0-10⁵ μS/cm. The aging temperatures were 0 to 98°C. After aging, the specimens were kept in air at room temperature for up to 4500 h during which the recovery of hydrophobicity and weight changes were measured. Specimens were also kept in high vacuum for 20 h to determine the changes in the contact angle and in the weight with the absence of air
