Carbon Nanotubes: IDTechEx Discusses if Bigger is Better

The sheets or veils can either have the CNTs aligned or not, the latter usually being in the form of an entangled non-woven mat. These are not new to the market nor new developments, but the VACNT (vertically aligned carbon nanotube) sheets are gaining some notable traction. NAWA Technologies, fresh from completing a Series C funding round in early 2022 and acquiring N12 Technologies in 2020, are expanding their capacity mainly for energy storage applications. Carbice Corporation raised an eye-catching $15m Series A in late 2020 and are targeting the use of VACNTs for thermal interface materials. Outside of niche use-cases, this material family remains as a solution looking for a commercial problem, but given the developments, they should not be overlooked.

The CNT yarns continue to spark much excitement, an example being Kureha's 2022 investment, but are still to gain any of the commercial success that their properties promise. An ultra-strong, conductive fiber is an attractive proposal, and there are numerous production processes at various stages of TRL & MRL. Many commercial companies employing a spinning process can trace their roots back to Rice University, including DexMat, Conyar, and Wootz. The other main approach is a 1-step CVD process employed by the likes of Nanocomp, acquired by Huntsman in 2018, and Tortech. Beyond the manufacturing challenges, the question will remain about where there is a market pull beyond relatively niche space, sporting, and e-textile applications.

Other comparable areas should not be ignored, namely very high aspect ratio nanotubes and hybrid products:
