In-Situ Polymerization
IN-Situ Polymerization is an especially effective way to construct a nanocomposite material. In this method the nanoparticle are fixed with some structure. The structure is impregnated with a monomer and the monomer polymerized. Usually the monomer is very fluid allowing imprgegnation without undue disturbing the nanoparticle arrangement. After polymerization, the material is finished with little necessary finishing. (RDC 5/4/2009)
