Stable liquid foams from a new polyfluorinated surfactant

Chem Commun (Camb). 2020 May 28;56(43):5807-5810. doi: 10.1039/d0cc02182b.

Abstract

Liquid foams exhibiting long-term stability are a key-challenge in material design. Based on this perspective, new pyridinium polyfluorinated surfactants were synthesized from simple building blocks enabling unusually stable liquid foams. While the batch-generated foams were used for qualitative foaming evaluation, microfluidics allowed a quantitative insight into the aging effects of monodisperse foams.
