Patent number: 11117289Abstract: The present disclosure provides methods for stabilizing a colloidal dispersion during transport for low defect tolerance applications. The methods involve eliminating fluid interfaces within a dispersion, storing the dispersion in an environment of inert gas, and degassing the dispersion. Several bottle closure devices are described which may be ideal for use with these methods, being able to seal a container filled with a dispersion, permit the removal of headspace and rapidly empty the contained dispersion. In one aspect, the device includes a vented cap and semi-permeable membrane, which allows the passage of gas into and out of the container, and a dispenser nozzle integrated with the device to allow a stored dispersion to be dispensed without removing the device from the container. In another aspect, the bottle closure device includes an attachment point for a removable downtube and dispenser nozzle.Type: GrantFiled: July 19, 2017Date of Patent: September 14, 2021Assignee: Nantero, Inc.Inventors: Billy Smith, David Cook, David A. Roberts, Thomas R. Bengtson

Patent number: 10124367Abstract: A method for arranging nanotube elements within nanotube fabric layers and films is disclosed. A directional force is applied over a nanotube fabric layer to render the fabric layer into an ordered network of nanotube elements. That is, a network of nanotube elements drawn together along their sidewalls and substantially oriented in a uniform direction. In some embodiments this directional force is applied by rolling a cylindrical element over the fabric layer. In other embodiments this directional force is applied by passing a rubbing material over the surface of a nanotube fabric layer. In other embodiments this directional force is applied by running a polishing material over the nanotube fabric layer for a predetermined time. Exemplary rolling, rubbing, and polishing apparatuses are also disclosed.Type: GrantFiled: August 19, 2016Date of Patent: November 13, 2018Assignee: Nantero, Inc.Inventors: David A. Roberts, Hao-Yu Lin, Thomas R. Bengtson, Thomas Rueckes, Karl Robinson, H. Montgomery Manning, Rahul Sen, Michel Pires Monteiro

Patent number: 9650732Abstract: The present disclosure provides methods for removing defects nanotube application solutions and providing low defect, highly uniform nanotube fabrics. In one aspect, a degassing process is performed on a suspension of nanotubes to remove air bubbles present in the solution. In another aspect, a continuous flow centrifugation (CFC) process is used to remove small scale defects from the solution. In another aspect, a depth filter is used to remove large scale defects from the solution. According to the present disclosure, these three methods can be used alone or combined to realize a low defect nanotube application solutions and fabrics.Type: GrantFiled: April 30, 2014Date of Patent: May 16, 2017Assignee: Nantero Inc.Inventors: J. Thomas Kocab, Thomas R. Bengtson, Sanjin Hosic, Rahul Sen, Billy Smith, David A. Roberts, Peter Sites
