These changes were explained by an increased electrostatic and steric repulsion between the aggregates formed at the air-100 mM NaCl interface due to the adsorption of negatively charged SiO2 NPs to the slightly positively charged TiO2 aggregates. The force-distance curves measured between a SiO2 probe and the sintered films of SiO2 and/or TiO2 NPs in a 1.0 mM NaCl solution adjusted to pH 4 showed that the magnitude of the repulsive force decreased with an increased number of TiO2 NPs in the film. This force change indicated that the surface
