High-strength plastic nanostructured materials process patented

Australia’s Eden Innovations Ltd. has received notice from the U.S. Patent Office that its patent application, filed in August 2017, entitled “Method For Making Nanostructured Materials Using Intercalation Of Carbon Nanoparticles” has been allowed. The method is particularly suited to the fabrication of high-strength plastic nanostructured materials and was developed by Eden in concert with the University of Queensland.

Eden’s carbon nanotube initially has been commercially employed in an admixture for concrete that significantly improves mechanical properties.

The company reports that this is a very important step in the proposed commercialization of its EdenPlast composites, providing protection in the USA (and any other jurisdictions in which a similar patent may be granted under the Patent Convention Treaty) of the patented methodology until August 2037.

The development of EdenPlast, which has taken a number of years, has produced a range of plastics that have had a number of their performance characteristics enhanced, including stiffness, elasticity and strength. Additionally, a masterbatch of highly concentrated nanoparticle-enhanced plastic (which is necessary for marketing a commercial product) has also been successfully developed. Target applications include automotive, aerospace, conductive coatings, packaging materials and batteries.

Eden’s pyrolysis process for carbon nanotube, carbon nanofiber and hydrogen production from natural gas without producing carbon dioxide is reportedly relatively efficient when compared with other methods of production of carbon nanotubes and fibers. Developed jointly by Eden and the University of Queensland and now owned 100% by Eden, the process has been commercialized in Colorado, at Eden Innovations LLC’s facility, where methane (natural gas) is broken down into its constituents of hydrogen gas and carbon, without the production of carbon dioxide. The carbon is produced as a solid in the form of either carbon nanofibers or carbon nanotubes that each are many times stronger, in certain applications, than steel, whilst each also has a great a capacity to conduct both electricity and heat.

Initial commercial application has been in the form of EdenCrete—a carbon nanotube-enriched admixture for concrete that significantly improves tensile and flexural strength without compromise to compressive strength, permeability or corrosion resistance. EdenCrete is being used by a number of general and shotcrete contractors in Colorado, and it has also been used in two highway repair projects in the state of Georgia.
