The preparation of stimulus-responsive Pickering emulsion and its application in preparing microspheres

Redox- and pH-responsive emulsions based on TiO2 nanoparticles and ferrocene derivates

“…25,36 Moreover, it should be noted that both zeta potential and specific surface area of unmodified TiO 2 nanoparticles were much higher than those of Fe 3 O 4 and SiO 2 nanoparticles, as shown in Table 1. 32,33,37 Therefore, there might be a stronger electrostatic interaction between TiO 2 nanoparticles and Fc + A, which enabled real-time modification of nanoparticles by Fc + A. In addition, the adsorption isotherm (Fig.…”

“…This corresponded to the molecular area of 2.91 nm 2 , which was higher than that of Fc + A at the air-water interface (1.68 nm 2 ), implying the monolayer adsorption. 37,39 The measurement of contact angle and zeta potential has proved the adsorption of Fc + A on the surface of TiO 2 nanoparticles. Was there this interaction between them during the formation process of emulsions?…”
