Youjie Sheng et al, studied how silica nanoparticles affect the properties of mixed solutions containing fluorocarbon and nonionic hydrocarbon surfactants. They found that while nanoparticles improved foam stability, they compromised foaming properties. The presence of nanoparticles at plateau borders enhanced foam drainage, coarsening, and mechanical strength. . In another study , the thermal stability of foams stabilized with mixed dispersions of SiO2 nanoparticles, nonionic surfactants, and fluorocarbon surfactants was investigated. The results showed that nanoparticles can prevent foam decay, drainage, and coarsening under heat, enhancing foam thermal stability.
