Publication number: 20230416493Abstract: Embodiments described herein relate generally to systems and methods for manufacturing a master batch with a graphitic material dispersed in a polymer matrix. In some embodiments, a method for manufacturing the master batch can include combining the graphitic material with a polymer, adding a supercritical fluid to the mixture, and depressurizing the supercritical fluid to remove the supercritical fluid. In some embodiments, the method includes mixing the graphitic material and the polymer for a first time period to form a first mixture and transferring the supercritical fluid to the first mixture to form a second mixture. In some embodiments, the method includes mixing the second mixture for a second time period and depressurizing the second mixture to allow the supercritical fluid to transition to a gas phase.Type: ApplicationFiled: February 14, 2023Publication date: December 28, 2023Applicant: NanoXplore Inc.Inventors: Seyed Mahdi HAMIDINEJAD, Chul B.

Publication number: 20230138169Abstract: Graphene-modified polymeric foam materials are provided that are amenable to conventional foams to yield articles with superior properties relative to like articles absent the graphene cell modifier. Graphene-based cell modifiers are incorporated in the polymer before or during the foaming process to not only improve the mechanical, thermal, electrical, fire retardant, or barrier properties of the polymer matrix itself, but also help modify the size, density, and morphology of cells in the foam, thereby tailoring the properties of the final foam articles. The graphene-modified polymeric foam materials may be utilized for the manufacturing of articles for mechanical, thermal, noise reduction, or sound absorption applications. The graphene-modified foams and articles made thereof have the advantages higher mechanical strength, better thermal stability, and better sound absorption properties as compared to the conventional polymeric foams such as materials made by copolymer polyol.Type: ApplicationFiled: February 16, 2021Publication date: May 4, 2023Applicant: NanoXplore Inc.Inventors: Scott Murray, Allan James, Liya Wang

Publication number: 20230092502Abstract: A graphene-based zinc containing coating is provided to prevent or slow down the corrosion of steel. The graphene-based materials are selected from a group of modified single-layer graphene, double-layer graphene, few layer graphene, graphene nanoplatelet, doped graphene, and a combination thereof. The modified graphene-based materials in zinc-containing paints or coatings act as a barrier to prevent or slow down the diffusion of corrosive species to the steel surface to be protected. For such a purpose, the graphene has a high aspect ratio and good structural integrity, especially a lack of defects on the basal plane of the graphene.Type: ApplicationFiled: February 3, 2021Publication date: March 23, 2023Applicant: NanoXplore Inc.Inventor: Liya Wang
