Foam Stabilization by Surfactant/SiO₂ Composite Nanofluids

This paper deals with the potential of aggregates of surfactant and SiO₂ nanoparticles as foam stabilizers for practical applications. The effects of different chain lengths and concentrations of the cationic surfactant CnTAB on the performance of CnTAB–SiO₂ nanofluids are examined to gain a comprehensive understanding of their ability to stabilize foam. The results indicate enhanced foam stability in the presence of SiO₂ nanoparticles. These findings help to better understand foam stabilization and its potential in various industrial applications such as enhanced oil recovery and foam-based separation processes.
