Carbon Nanotube Air Filter Neutralizes Betacoronavirus
Researchers at the University of Cambridge, in collaboration with Tortech Nano Fibers Ltd. and Q-Flo Limited, have developed a self-sanitizing carbon nanotube (CNT) air filter that can achieve full deactivation of a betacoronavirus and adeno-associated virus. The CNT filter prototype achieved 99% air purification of a room within 10 minutes. The filter is a major breakthrough in the fight against respiratory diseases, including COVID-19. The University of Cambridge team developed a mass-producible air filter that displays commercial HEPA pressure drop and efficiency while being self-sanitizing. The filter can be flash heated to 1300C within seconds, leading to full viral inactivation. The research focuses on the use of carbon nanotubes as an effective filtration material for capturing and neutralizing viral and other pathogenic threats.

Q-Flo: progress towards a materials revolution - Cambridge Enterprise
Q-Flo, a University of Cambridge spin-out, has been working on novel technology to create continuous and self-assembled carbon nanotubes. The company has partnered with TorTech Nano Fibers to scale up production. Through further research, Q-Flo discovered that the later part of the production process was more important for increasing production rates. This led to the launch of the Advanced Nanotube Application and Manufacturing Initiative (ANAM) in 2014, which received funding from EPSRC and industrial partners. The ANAM Initiative involves multiple faculty members from the University of Cambridge and the University of Ulster, as well as commercial partners such as TorTech, Siemens, BAE Systems, and Marshall Aerospace and Defence. The collaboration between all parties has been successful in accelerating process development and facilitating commercial activity.

Tortech Nanofibres Installs Additional Capacity for Manufacture of Nonwoven Carbon Nanotube Sheets
Tortech Nanofibres, a subsidiary of Plasan, is expanding its manufacturing capacity for nonwoven carbon nanotube (CNT) sheet. The installation of additional capacity will more than triple output and is a step towards full-scale industrial manufacturing. The company is developing a chemical engineering process to produce a unique material that will be cost competitive with conventional carbon fiber materials. Tortechs nonwoven CNT sheet has properties such as electrical conductivity, high EMI attenuation, black body radiation, and IR suppression, making it useful in various market sectors. It is particularly suited for EMI shielding, with exceptional attenuation across a wide frequency range. The material also has heat dissipation properties and can be used for stealth and thermal camouflage applications. When incorporated into composites, it adds strength and toughness to carbon fiber. The properties of Tortechs CNT sheet can be tailored to meet customer requirements.
