Research Abstract

A new processing route to disperse inorganic salt species in organic solvents in nano-size was developed. First, nanoparticle with localized hydrophilic pool structures on their surfaces were synthesized by using surfactants with PEG structures. Then, inorganic salts were deposited in the localized hydrophilic pool structures. The prepared nano-sized salts are expected to possess their functional properties in organic solvents due to their high salt/solvent interface area.
