Foam Stabilization by Surfactant/SiO2 Composite Nanofluids

This research 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 C_nTAB on the performance of C_nTAB–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.本研究探讨了表面活性剂与二氧化硅（SiO2）纳米颗粒聚集体作为泡沫稳定剂的实际应用潜力。本研究考察了不同链长与浓度的阳离子表面活性剂C_nTAB对C_nTAB–SiO2纳米流体性能的影响，以全面理解其稳定泡沫的能力。实验结果表明，当体系中存在SiO2纳米颗粒时，泡沫稳定性得到显著提升。上述研究结果有助于进一步明晰泡沫稳定机制及其在强化采油、泡沫基分离工艺等诸多工业领域的应用潜力。
