摘要：

Nanoparticles (NPs) adsorbed at bubble surface have a substantial impact on gas-liquid interface properties, but how to regulate the properties and further control foam flow remaining to be elucidated. Here, the effects of nanoparticle surfactancy on surface rheology, fluidity and shear force field around bubbles were quantitatively analyzed. It was found that the adsorption of nanoparticles on the bubble surface gives rise to surface solidification, the flow velocity close to surface decreased by 76%, meanwhile the shear stress loaded on bubble surface increases sharply. Furthermore, the surface solidification degree or fluidity can be controlled by regulating the packing density of nanoparticles on bubble surface, whereby the bubble flow could be control accordingly, which greatly contribute to the application of foam.
