Abstract
A metal nanoparticle colloid solution, metal-polymer nanocomposites, and methods for preparing the same are provided. The metal nanoparticle colloid solution and the metal-polymer nanocomposites can be prepared with a variety of polymeric stabilizers and have uniform particle diameter and shape. The metal nanoparticle colloid solution and the metal-polymer nanocomposites have wide applications, for example, as an antibacterial agent, a sterilizer, a conductive adhesiv, conductive ink or an electromagnetic wave shielder for an image display.
Claims11
A method for preparing metal-polymer nanocomposites, comprising:
- dissolving a metal salt and a polymeric stabilizer in a solvent mixture of water and a non-aqueous solvent;
- purging a reaction container containing the solution with nitrogen or argon gas;
- and
- radiating radioactive rays onto the solution to obtain precipitates, wherein said polymeric stabilizer is selected from the group consisting of polyethylene, polyacrylonitrile, poly(methyl (meth)acrylate), polyurethane, and polyethylene glycol.
