제목 Interfacial Phase Behavior of Anisotropic Nanoparticles at Air/Water Interface and Mechanical Properties of Nanoparticle-Stabilized Droplets
초록 Amphiphilic dumbbell-shaped polystyrene nanoparticles were synthesized and the mechanical properties of nanoparticle-stabilized emulsion were investigated for the purpose of an emulsifier in cosmetics. The interfacial phase behaviors at the air-water interface such as surface activity, colloidal clustering, and film assembly were studied with the chemically tunable anisotrophic and geometrically symmetric nanoparicles. Due to the jamming property of nanoparticles at the oil-water interface, the mechanical behavior of nanoparticle-stabilized droplets (pickering emulsion) exhibit a two-stage response to increaseing suction pressure using micropipette aspiration.
