Abstract
A downhole tool includes a sensor having a sensitive component, a polymer that at least partially covers the sensitive component, and a hydrophobic material impregnated within the polymer and/or the sensitive component of the sensor. Methods of forming the downhole tool include covering a portion of the sensor with a polymer and impregnating a hydrophobic material within the polymer and/or the sensitive component of the sensor.
