Publication number: 20100009165Abstract: Methods for making multifunctional nanomaterial-containing composites that include the incorporation of nanomaterials into such composites in at least one of two manners: 1) in a solution of dispersed nanomaterials for coating onto a substrate; and 2) by dispersing nanomaterials in a matrix material, such as epoxy, applied to a single substrate layer or sandwiched between adjacent layers in a multiple layer composite. According to such methods, a high loading of nanomaterials may be incorporated into the composites without any deterioration in processing or handling properties.Type: ApplicationFiled: July 10, 2008Publication date: January 14, 2010Applicant: ZYVEX PERFORMANCE MATERIALS, LLCInventors: Pritesh PATEL, Gobinath BALASUBRAMANIYAM, Jian CHEN

Publication number: 20080194737Abstract: A new, non-wrapping approach to solubilize nanotubes, such as carbon nanotubes, in organic and inorganic solvents is provided. In accordance with certain embodiments, carbon nanotube surfaces are functionalized in a non-wrapping fashion by functional conjugated polymers that include functional groups for solubilizing such nanotubes. Various embodiments provide polymers that noncovalently bond with carbon nanotubes in a non-wrapping fashion. For example, various embodiments of polymers are provided that comprise a relatively rigid backbone that is suitable for noncovalently bonding with a carbon nanotube substantially along the nanotube's length, as opposed to about its diameter. In preferred polymers, the major interaction between the polymer backbone and the nanotube surface is parallel ?-stacking. The polymers further comprise at least one functional extension from the backbone that are any of various desired functional groups that are suitable for solubilizing a carbon nanotube.Type: ApplicationFiled: July 10, 2007Publication date: August 14, 2008Applicants: ZYVEX PERFORMANCE MATERIALS, LLC, University of Pittsburgh - Of the Commonwealth System of Higher EducationInventors: Jian Chen, Haiying Liu
