Patent number: 10815356Abstract: A gas barrier material includes an atomic sheet, such as graphene and/or an analog of graphene. The gas barrier material can be arranged as part of a component, such as a container or other vessel, to limit the flow or permeation of gas through the component. Where the component is a container or part of a container, the gas barrier material may be formulated and arranged to limit or prevent gas ingress or egress with respect to the internal volume of the container. The atomic sheet offers improved gas barrier properties compared to traditional polymeric barrier materials and is particularly useful in applications where it is desired to limit permeation of small gas molecules such as helium, such as airships or other lighter than air vehicles.Type: GrantFiled: January 27, 2017Date of Patent: October 27, 2020Assignee: Lockheed Martin CorporationInventors: Steven Edward Bullock, Jaime Ballester

Patent number: 10653824Abstract: Various systems and methods relating to two-dimensional materials such as graphene. A membrane include a cross-linked graphene platelet polymer that includes a plurality of cross-linked graphene platelets. The cross-linked graphene platelets include a graphene portion and a cross-linking portion. The cross-linking portion contains a 4 to 10 atom link. The cross-linked graphene platelet polymer is produced by reaction of an epoxide functionalized graphene platelet and a (meth)acrylate or (meth)acrylamide functionalized cross-linker.Type: GrantFiled: April 14, 2016Date of Patent: May 19, 2020Assignee: Lockheed Martin CorporationInventors: Peter V. Bedworth, Steven Edward Bullock, Sarah M. Simon, Steven W. Sinton, John B. Stetson, Jr., Jacob L. Swett, Scott E. Heise

Patent number: 10023267Abstract: Systems and methods of reducing drag on outer surfaces of vehicles that are in contact with water using a polymer solution that reduces the drag on the outer surfaces of the vehicles as the vehicles travel through water. A polymer solution is passively ejected into the boundary layer of the water flowing past the outer surface of the vehicle. The polymer solution is mixed and introduced into the boundary layer passively with minimal or no usage of electrical energy. The passive mixing and ejection of the polymer solution minimizes energy consumption, thereby maximizing electrical energy consumption efficiency during operation of the vehicle.Type: GrantFiled: September 2, 2016Date of Patent: July 17, 2018Assignee: Lockheed Martin CorporationInventors: John C. Brandes, Steven Edward Bullock, Joseph M. Cuschieri, Vincent J. Forst, Brian Robert Said, Joseph M. Solenski

Patent number: 9574063Abstract: Large area graphene (LAG) sheets can be embedded in a polymer-based material as a mechanical reinforcement or to otherwise enhance the properties of the polymer-based material. The LAG sheets can be nanoperforated and/or functionalized to enhance interaction between the graphene and the polymer. Reactive functional groups can facilitate formation of covalent bonds between the graphene and the polymer so that the LAG sheets become an integral part of the cross-linked structure in curable polymer-based materials. Nanoperforations in the LAG sheets provide useful sites for the functional groups and can allow cross-links to form through the nanoperforations.Type: GrantFiled: September 17, 2013Date of Patent: February 21, 2017Assignee: Lockheed Martin CorporationInventors: Steven Edward Bullock, Clinton M. Newell
