The Hydrophobic Mystery Discovering the Nature of Silicones

Silicones consist of two non-polar methyl groups and two polar hydroxyl groups, making them insoluble in water due to electrostatic repulsions. They are thermally stable, resistant to oxidation, and have a high dielectric constant. Silicones are used in grease, surgical instruments, seals, electric motors, and enamel paints.
