Particle and Particle-Surfactant Mixtures at Fluid Interfaces: Assembly, Morphology, and Rheological Description

Figure 3

Dependences of the surface tension of the water/hexane interface on the PA concentration: PA (○, the solid lines represent the fitting of the experimental data to the Frumkin adsorption isotherm) and silica nanoparticles-PA mixtures (●). The particle concentration in the bulk was 1 wt%. Reproduced from [49], Copyright 2014, with permission from Elsevier.
