【 摘 要 】

Janus silver (Ag) nanoparticles have been successfully synthesized by intense agitation at the interface of toluene and water which contains Ag (PPh3)2NO3and THPC. Contact angle of the film prepared by L-B technology is measured which indicates that the Ag nanoparticle is amphipathicity because they have hydrophobic region and hydrophilic region separately. TEM image showed the assembled morphology of Ag instead of monodispersed particles. After purification, analysis of FT-IR and XPS showed the Janus Ag nanoparticles are protected by ligands of THPC and PPh3with a ratio of 1:1.
