This study explored the fabrication of bi-phase dispersible Ag-nanospheres (AgNSs) by ionic surfactant-induced surface activity and unique molecular interactions. Different kinds of ionic surfactants were tested to check whether spherical shape could be produced, and size distribution uniformity could also be achieved. Furthermore, surface activity of the AgNSs prepared in aqueous solution was investigated by observing whether representative molecular interactions could lead to phase transfer of the AgNSs from aqueous to non-aqueous solution. Results from characterization techniques of a scanning electron microscope and a transmission electron microscopy indicated that the use of anionic surfactants resulted in better qualities in terms of spherical shape maintenance and size uniformity than the use of cationic surfactant, and the concentration of the added surfactants seemed not to be relevant to the quality of final product. Lastly, covalent bonding mediated interaction showed better performance on phase transfer than electrostatic interaction, producing the AgNSs successfully dispersed in non-aqueous solution. |
