What are the properties of perfluorocarbons?
Perfluorocarbons are synthetic, fluorinated hydrocarbons that increase the amount of oxygen dissolved in the fluid phase of the blood. Perfluorocarbon emulsions are heavy, low-viscosity liquids, inert, and optically clear, with a high specific gravity and good surface tension.
Why are fluorocarbons Lipophobic?
As a result, fluorocarbons have low intermolecular attractive forces and are lipophobic in addition to being hydrophobic and non-polar. Reflecting the weak intermolecular forces these compounds exhibit low viscosities when compared to liquids of similar boiling points, low surface tension and low heats of vaporization.
What is perfluorodecalin?
Perfluorodecalin is a fluorocarbon that is decalin in which every hydrogen is replaced by fluorine. Capable of dissolving large quantities of oxygen, it has been used as the basis of an artificial blood substitute. It has a role as a blood substitute and a solvent. It derives from a hydride of a decalin. ChEBI.
Is perfluorocarbon safe?
Health and Safety Perfluorocarbons (PFCs) are chemically inactive, nontoxic, and nonflammable compounds that are found in the atmosphere at very low levels. PFCs present no known danger to humans if inhaled or ingested.
What are perfluorocarbons used for?
Perfluorocarbons are powerful greenhouse gases that were introduced as alternatives to ozone depleting substances. PFCs replace chlorofluorocarbons (CFCs) in manufacturing semiconductors. They are also used as solvents in the electronics industry, and as refrigerants of some specialized refrigeration systems.
How do fluorocarbons work?
A fluorocarbon product based on a urethane backbone is then applied to reduce the surface energy of the fibre. The fluorocarbon finish limits the penetration of aqueous and oily spills, and also facilitates soil removal in cleaning.
What are fluorocarbons used for?
Fluorocarbons are fluorinated carbon chain polymers that are used in an assortment of household and commercial products as waterproofing agents, lubricants, sealants, and leather conditioners.
Is Perfluorodecalin good for skin?
The fact that perfluorocarbon enhances the oxygen-carrying abilities of skin cells is what makes it incredibly effective in wound healing. Several studies have proven that applying oxygen to wounds can significantly improve healing and even reduce the risks of infection.
What is perfluorocarbon liquid?
Perfluorocarbon liquids (PFCLs) are a serial of fluorochemicals in which all the hydrogen atoms are replaced by fluorine [1]. PFCLs are not found in nature. Those compounds are industrially produced by methods such as electrochemical fluorination, oligomerization, and telomerization [2].
Where are PFCs found?
PFCs have been found in rivers and lakes and in many types of animals on land and in the water. How people can be exposed to PFCs is as yet unclear. Some PFCs persist in the environment, and people are mostly likely exposed by consuming PFC-contaminated water or food.
Where are PFCs used?
For example, PFCs may be used to keep food from sticking to cookware, to make sofas and carpets resistant to stains, to make clothes and mattresses more waterproof, and may also be used in some food packaging, as well as in some firefighting materials.
