The intercalation of the oligomer or polymer then increases the spacing of adjacent layers an additional at least 3 Å, e.g., to at least about 20 Å, preferably about 25 Å to about 30 Å, generally about 28 Å, and provides a nanocomposite having increased tensile strength, flexibility, and ductility (less brittle).Type: GrantFiled: March 1, 2000Date of Patent: June 18, 2002Assignee: Amcol International CorporationInventors: Guoqiang Qian, Tie Lan, Aaron M.
