Abstract

In this paper a melt-blown technique was used to fabricate a non-woven veil with 5 wt.% of multi-walled carbon nanotubes. The main aim was to describe this approach which does not use chemicals or additional polymer, but instead used simple dilution of Masterbatch by neat polymer. It was observed that the ratio of Masterbatch used to neat polymer affects the final microstructure of the veil. Moreover, by using a Scanning and Transmission Electron Microscope the effect of one screw in the machine on dispersion and distribution of carbon nanotubes was analyzed. Additionally, a comparison between the obtained veils and similar products available on the market is given. The melt-blown technique is commonly used as fast, low cost method and can easily be up-scaled for the processing of thermoplastic nanocomposites with carbon nanotubes. In turn, the final carbon nanotubes doped veil product is a desired structure which can be used as an interlayer in reinforced multifunctional composites, and especially for its electrical properties. Due to their stickiness and flexibility they are perfect nanocarriers of carbon nanotubes for the resin infusion process applied in laminate fabrication.
