Core, impact resistance and bending strength at yield improved compared to the standard formula- tion,” Edwards says. In TPU with 1% GraphCore, tests have shown an 80% improvement in abrasion resistance compared to a standard formulation. In an inflatable TPU application, the additive provided both weight reduction and puncture improvement. Black Swan Graphene was set up in 2021 as a joint venture between UK chemical company Thomas Swan, which was a pioneer in graphene production, and Canada’s Mason Graphite to rapidly expand production of bulk graphene from graphite. Edwards says the company’s production technology has the capability to produce graphene from various sources of graphite, ranging from mine-flakes to off-cuts from anode production. “This ability to work with different sources of
graphite helps guarantee our supply, particularly as demand for graphite for battery anode production grows,” he says. The company operates a pilot plant in the UK with
more than 40 tonnes/yr capacity and has just completed a scoping-study stage for a commercial production facility to be built in Quebec, Canada, close to both low-cost hydroelectric power and its graphite source. The plan is to build a 3,700m2 facility that will use the same technology as the UK plant but with a capacity of close to 10,000 tonnes/yr.
Shielding options Production of plastic parts with an inherent capabil- ity to shield electronics from electromagnetic interference (EMI) is a potential “good fit” applica- tion area for graphene-enhanced composites.
Earlier this year, Portuguese graphene technology
company Graphenest received €1.8m in funding to scale-up production and business development for graphene-based EMI-shielding products. Plastics containing graphene provide better shielding effectiveness, are lighter weight, and reduce production costs compared to traditional metal systems, the company says. It sees potential applica- tions in areas such as 5G/6G cables and wiring, housings for batteries and electronics, and printable electronics for radar and LiDAR sensors. Graphenest has partnered with UK-based black masterbatch and compound producer Hubron to develop masterbatches and compounds for EMI shielding for e-mobility and electronics. Work in this area will begin with a graphene-based PP. The G+Board project from the EU’s Graphene
Flagship research initiative was established to develop a graphene-based conductive composite automotive dashboard with lighter weight. The pro- ject targets electric vehicles in particular and participants include car maker Stellantis, which is collaborating with Lyten (which manufactures a 3D graphene product) and others to apply Lyten’s 3D Graphene materials to automotive applications. The G+Board automotive dashboard design
replaces copper wiring with graphene-based integrated conductive paths, sensors, and switches to reduce the number of production steps required and to improve recyclability. Graphene is embed- ded into the polymer and a laser treatment used to selectively modify the electrical conductivity to provide the required circuits. Project leaders say that the project, which was originally launched in 2020, is now showing promise in terms of industrial applica-
