A new synthesis method for a clay/polymer nanocomposite that has excellent physical properties has been introduced. Free radical polymerization occurs on the surface of various particles which include spherical particles; SiO2, rod-like particles; imogolite and halloysite, plate-like particles; clay and graphene. The hydroxide groups on the surfaces can be changed to peroxide groups by gamma ray radiation in an aqueous solution. These peroxide groups changed to oxide radicals after the temperature was increased above 40 �C, which acted as both initiators and crosslinkers. A 3D network was ultimately formed after propagation from the surfaces and sporadic polymerization. Clay particles and nanocomposite were characterized by light and x-ray scattering methods, and their chemical properties were characterized by Raman spectroscopy, and their mechanical properties were examined by universal test machine.
