- 摘要：
- We have investigated the formation and evolution of zinc oxalate particles in internal aqueous droplets and their effects of emulsion interface properties. The formation of particles follows an aggregation-controlled mechanism that depends on the size of droplets and surfactant. The size of droplets determines the final shape of the particles by affecting the supersaturation ratio to form rod-like and sheet-like particles. The surfactant adsorbed on the particles changes the wettability, leading to the aggregation of the primary particles at the internal water-oil interface. Moreover, the adsorption can cause a higher level of impurity and defects in as-synthesized particles. This effect could be directly employed to fabricate heterojunction rectifier.
