Publication number: 20100196611Abstract: A process of forming a composite material comprising treating pristine clay with water to form a swollen clay, intercalating the swollen clay with an organic solvent to form an organic solvent intercalated swollen clay by exchanging the water with the organic solvent while maintaining the swollen clay in a swollen state with the solvent. The organic solvent intercalated swollen clay is then treated with a silane coupling agent and the organic solvent intercalated swollen clay so modified is mixed with an epoxy matrix material to form a nanocomposite. The nanocomposite is then applied to a reinforcing material to thereby form a composite material.Type: ApplicationFiled: March 12, 2010Publication date: August 5, 2010Inventors: Nopphawan Phonthammachai, Chaobin He, Xu Li
