Zyvex Technologies (Columbus, OH, US) has launched a new product family called ZNT (Zyvex nanotube technology), a polymer modified carbon nanotube additive for a range of host matrices that includes epoxies, elastomers, thermoplastics and aqueous-based solutions. Zyvex argues that carbon nanotubes have been touted as performance-enhancing additives, but have seen limited success due to poor nanotube dispersion and lack of adhesion to the matrix material. The ZNT family of products is said to enable easy and cost effective dispersion of carbon nanotubes for true performance increases at affordable prices. Zyvex notes that many CNT suppliers, including Zyvex, have been hesitant to provide their fundamental technology to other organizations without complex licensing models; ZNT is said to provide a more open-source approach, which it hopes will lead to greater and faster advances in its adoption. ZNT is available in four customizations: ZNT-C for thermoset composites, epoxies and vinyl/poly esters; ZNT-W for aqueous based applications; ZNT-Ep for peroxide cured elastomers; and ZNT-Es for sulfur-cured elastomers.
