Synthesis and testing of hydrolysis resistant siloxane Surfactants as Additives for Pool Fire Suppression

Abstract

Perfluoroalkyl surfactants are the key ingredients in aqueous film forming foams (AFFF) which are used by the Department of Defense and others to fight hydrocarbon (Class B) pool fires.Perfluoroalkyl surfactants work extremely well for this application, however there are growing concerns about these materials because they are highly persistent in the environment and may be toxic to plants and animals or increase their risk to certain diseases. The objective of this project was to explore hydrolysis-resistant siloxane surfactants asreplacements of perfluoroalkyl surfactants found in current aqueous film forming foam (AFFF)concentrates used in fire-fighting by the Department of Defense (DoD). The new, stable siloxane surfactants produced in this research will contain only the elements carbon,silicon, hydrogen and oxygen.
