Patent number: 8617652Abstract: Embodiments relate to depositing on one or more layers of materials on a fiber or fiber containing material using atomic layer deposition (ALD) to provide or enhance functionalities of the fibers or fiber containing material. A layer of material is deposited coated on the fibers or fiber containing textile by causing the relative movement between a fiber or the fiber containing textile and a source injector. The surface of the material is oxidized, nitrified or carbonized to increase the volume of the deposited material. By increasing the volume of the material, the material is subject to compressive stress. The compressive stress renders the fibers or the fiber containing material more rigid, stronger and more resistant against bending force, impact or tensile force.Type: GrantFiled: June 28, 2012Date of Patent: December 31, 2013Assignee: Veeco ALD Inc.Inventor: Sang In Lee
