Patent number: 7459121Abstract: Methods and devices are provided for the continuous production of a network of nanotubes or other nanoscale fibers. The method includes making a suspension of nanoscale fibers dispersed in a liquid medium, optionally with surfactant and/or sonication, and filtering the suspension by moving a filter membrane through the suspension, such that the nanoscale fibers are deposited directly on the filter membrane as the fluid medium flows through the filter membrane, thereby forming a continuous membrane of the nanoscale fibers. The deposition of the nanoscale fibers can occur when and where the filter membrane moves into contact with a static, porous filter element or a dynamic, porous filter element. The filtering can be conducted within a magnetic field effective to align the nanoscale fibers, and/or with the aid of vacuum to pull water through the filter membrane, applied pressure to press water though the filter membrane, or a combination thereof.Type: GrantFiled: July 20, 2005Date of Patent: December 2, 2008Assignee: Florida State University Research FoundationInventors: Zhiyong Liang, Ben Wang, Chun Zhang, Jonnattan T.

Publication number: 20080280115Abstract: A technique is provided for the fabrication of multi-walled carbon nanotube (MWNT) and carbon nanofiber (CNF) film materials. The method includes mixing a relatively small amount of single-walled nanotubes (SWNTs) with larger amounts of MWNTs and CNFs, which enables one to produce highly flexible SWNT materials—advantageously without the need for bonding agents and at significantly lower costs compared to flexible SWNT materials. The method exploits SWNTs tendency to entangle together to form flexible films, using a small amount of SWNTs to wrap around and entangle the larger diameter MWNTs and CNFs together to form flexible films with highly beneficial mechanical, electrical, and thermal properties at a fraction of the cost of SWNT materials.Type: ApplicationFiled: February 2, 2007Publication date: November 13, 2008Applicant: FLORIDA STATE UNIVERSITY RESEARCH FOUNDATIONInventors: Zhiyong Liang, Ben Wang, Chun Zhang, Chreng-Shii Yeh
