The morphology of nanoparticles plays a significant role in the properties and applications Pickering emulsions. Oil-in-water (O/W) emulsions were prepared using spherical, rod-like, thread-like mesoporous silica (MSNPs) combination with cationic surfactant dodecyltrimethylammonium bromide (DTAB) as stabilizer. effects nanoparticle on stability stimuli-responsive investigated. For spherical rod-like MSNP systems, stable obtained at DTAB concentrations above 0.2 mmol·L-1. Stable containing...
Novel oil-in-water (O/W) Pickering emulsions (PEs) were prepared using mesoporous nanosilica in combination with a pH-insensitive cationic surfactant as stabilizer and show an interesting sensitivity to acids bases. Adding suitable amount of NaOH (nNaOH/ncationic ≥ 1) led prompt demulsification within 10 s. Upon further adding HCl solutions (nHCl/nNaOH = 1), stable PEs re-formed after homogenization. These remained for over 30 days 60 cycles, switching from unstable back states, showed high...
The combination of hydrophilic particles and surfactants provides a simple method to stabilize Pickering emulsions. type concentration the play important roles in microstructure rheological properties resulting Herein, stable n-octane-in-water emulsions with tunable were prepared using thread-like mesoporous silica nanoparticles (TMSNPs) cetyltrimethylammonium bromide (CTAB) as emulsifiers. CTAB (CCTAB) highly affected emulsions, which divided into three regions according results...
