While carbon nanotubes have long been regarded as a "miracle material," their benefits have been difficult to realize absent a practical manufacturing platform. The development of CHASM's V2V (Viscous-2-Vapor) ink technology provides such a platform. CNTs, remaining dispersed in V2V, can be easily screen printed using existing technology to facilitate the development and manufacturing of a broad range of transparent conductive film solutions. For applications where transparency, conductivity, AND flexibility are all required this platform is creating a new material category—Flexible Hybrid Transparent Conductive Films.
While ITO (Indium Tin Oxide ) has long satisfied the needs of the PCAP and transparent electrodes markets, the next generation of devices is more demanding. End users continue to demand improvements in device form factor, physical adaptability, performance, and price. To satisfy these requirements, a new material is required that is not only transparent and conductive, but also flexible, formable and more cost-effective to design and manufacture. CHASM's AgeNT TCF platform is leading this charge.
CHASM's Signis single-wall carbon nanotubes have long been a standard platform material for chemiresistor sensors because of their predictable resistance, and, in the case of SG65i, semiconducting CNT content. These CNTs can be dispersed into the company's patented V2V ink vehicle without the need for surfactants, enabling cost-effective, high-volume production of using widely available screen printing technology.
Specially designed patterns of CHASM's CNT and AgeNT hybrid transparent conductive films have been shown in anechoic chamber tests to redirect up to 95% of RF energy across a broad range of radio spectrum. This is particularly beneficial for users of smartphones which by design transmit RF signals omnidirectionally, exposing those users to substantial RF energy over time.
