Abstract
This invention provides combinations of fluorinated oils and fluorinated surfactants that have densities of approximately unity (1.0±0.1 kg/liter), where the combination allows the surfactant to dissolve (at least) to 1-2% level (by volume) in the oil.
Claims4
A fluid comprising molecules containing carbon, hydrogen, oxygen, silicon and fluorine, wherein said fluid has
- (i) a density between 0.95 and 1.05 grams/milliliter at 25° C. under 1 atmosphere of pressure,
- (ii) a viscosity less than 80 centistokes, and
- (iii) wherein said molecules show molecular weight distributions as measured by gel permeation chromatography centered near 300 and 10,000 grams/mol.
