Graphene 3D lab files patent for a 3D printer that can print a graphene-based OLED

Graphene 3D Lab has announced filing a provisional patent for a process of 3D printing an OLED light source that immediately functions when printed, with a graphene coated transparent conductor window. This unique structure is the product of an innovative multi-functional 3D Printer, which can make thin films as well as 3D structures.

The printer patent relates to a technology that should lead the industry in multiple deposition techniques, robotic manipulator, laser and UV curing capabilities. G3L considers the new IP a dramatic leap forward, offering the ability to 3D print with multiple functional materials at the same time, including the ability to 3D print a working light. This printer was reportedly designed to maximize the attributes of the functional materials that the company already developed, and plans to introduce in the future to the market.

Haydale HDPlas® process granted European patent for wide range of nanoparticles

Haydale announces that it has received confirmation from the European Patent Office (EPO) of the decision to grant a European Patent for its proprietary HDPlas® functionalization process for graphene and other nanoparticulate materials.

The European Patent is the key process patent underlying the Company's proprietary functionalization treatment and is one of a number arising from the families of patent applications surrounding Haydale's unique plasma functionalization process. Haydale already has a granted patent in China and has visibility on the patent application in Australia, which is expected to proceed to grant within the next 3-4 months.

Graphene 3D Lab files patent for graphene manufacturing

Graphene 3D Lab has filed a non-provisional patent relating to the preparation and separation of atomic layers of graphene. This technology is said to represent a new, energy-efficient process to manufacture, sort and classify graphene nanoparticles, resulting in the potential for large-scale production of high-grade graphene.

The patent is relevant to graphene nanoplatelets - it covers a new, energy-efficient, non-chemically invasive process that significantly lowers the cost of preparing and separating high-quality, low atomic layers of GNP.

LG files a patent for graphene microwaves

A newly published patent filing from LG reveals the specifications for a next-gen microwave oven that includes a graphene door to prevent the radiation inside from leaking out, ensuring more uniform heating. While the microwave itself sounds interesting, it seems that the manufacturing process, which follows a special layering approach, is the real innovation.

The process begins when a catalyst metal with microwave shielding properties such as copper is sandwiched between two layers of graphene synthesized by CVD. Next, a number of support materials are added to the structure in order to support the subsequent etching phases, which pattern the individual layers in a way that exposes both the graphene absorbent and the catalyst metal with its shielding properties for double effect.
