Claims7
A method for preparing metal nanoparticles in a drying oil, comprising the steps of:
- (a) mixing a solution comprising metal ions with a solution comprising a drying oil in the presence of an organic solvent or
- mixing a solution comprising an organometallic compound with a solution comprising a drying oil in the presence of an organic solvent;
- (b) agitating the mixture for a period of 12 to 24 hours;
- and
- (c) polymerizing the drying oil by autoxidation to form metal nanoparticles in the polymerized oil,
- wherein the method does not include an external reducing agent.
