Molecular Dynamics Simulations of the Short-Chain Fluorocarbon Surfactant PFHXA and the Anionic Surfactant SDS at the Air/Water Interface [PDF]

open access: yesMolecules
The research and development of alternatives to long-chain fluorocarbon surfactants are desperately needed because they are extremely toxic, difficult to break down, seriously harm the environment, and limit the use of conventional aqueous film-forming ...

Measuring Molecular Forces With Atomic Force Microscopy 1: Solvent Influence on Hydrophobic Interactions. [PDF]

open access: yesMicrosc Res Tech
Atomic force microscopy enables precise evaluation of the magnitude and range of hydrophobic and van der Waals interactions. This primer presents a protocol for fluorocarbon functionalization of gold surfaces and examines how water: DMSO mixtures affect hydrophobic forces, with data interpreted through an extended van der Waals model.

Adsorption Behavior of Fluorocarbon Surfactants on Polytetrafluoroethylene Surface

open access: yesColloids and Interfaces
By using the sessile drop method, the wetting properties of nonionic fluorocarbon surfactants (FNS-1 and FNS-2) and anionic fluorocarbon surfactant (FAS) solutions on the surface of polytetrafluoroethylene (PTFE) were investigated. Meanwhile, the effects
