Study on Aqueous Film Forming Foam Extinguishing Agents Based on Perfluorobranched Short-Chain Fluorocarbon–Hydrocarbon Surfactant Complex Mixtures

Langmuir
Aqueous film-forming foam (AFFF) is a targeted product for liquid fuel fires and has the benefits of a long storage period and high fire extinguishing efficiency. However, because of the toxicity and bioaccumulation of the core raw material's long-chain fluorocarbon surfactant, traditional AFFF is being phased out.

Micro-structure characteristics and the fire-extinguishing performance of aqueous film-forming foam mixed with short-chain fluorocarbon surfactant

Physics of Fluids
The environmental persistence of perfluorinated compounds derived from long-chain fluorocarbon surfactants in aqueous film-forming foam (AFFF) necessitates the development of eco-friendly alternatives. The short-chain fluorocarbon surfactants (C < 8) are promising substitutes due to their reduced bioaccumulation potential while maintaining ...

Effect of low pressure on the properties of short‐chain fluorocarbon surfactants and their application in aqueous film‐forming foam extinguishing agent

Journal of Surfactants and Detergents
AbstractSurface properties of three fluorocarbon surfactants with different carbon chain lengths were studied at low pressures of 94.6, 74.1 and 61.0 kPa, respectively. The results showed that the saturation adsorption capacity and the critical micelle concentration (CMC) decreased, while the average molecular area (AS) and the surface tension at CMC ...
