In this work, oil-in-water and water-in-oil emulsions stabilized by hydrophilic and amphiphilic silica nanowires separately were investigated by scanning electron microscopy (SEM), optical microscopy and visual observation. The effects of length, concentration and wettability of the nanowires on the stabilization of the emulsion were investigated. The hydrophilic silica nanowires of 10μm length can...
Double-shell composite microcapsule with a ripened CaCO 3 nanoparticle outer shell and melamine formaldehyde (MF)/copolymer inner shell shows advantages in adjustable permeability and mechanical strength, comparing with single shell microcapsules. Here, we have systematically studied the effects of certain formulation parameters on the properties of the double-shell composite microcapsules,...
Monodisperse ellipsoids were synthesized by continuous coating of silica on hematite spindle cores. Spindle cores with decreasing aspect ratio were obtained by decreasing the molar ratio of Fe 3+ and H 2 PO 4− . Using PVP molecules as the surface stabilizer for silica coating, the aspect ratio of the ellipsoids can also be tuned by altering the amount of added TEOS. These...
