Application

Our high-purity functionalized multiwalled carbon nanotubes can be used for nanocomposites to increase electrical conductivity or mechanical properties given its high conductivity and aspect ratio. Its functionalization allows stable formulations during your nanocomposite preparation. For instance, this product has shown stability within a gelatin based bioink: not observed any change in impedance over 6 months of real time and 3 years of accelerated time.
