- Аннотация: A pioneering synthetic approach for the design of novel composite materials is reported. The final products are consisting of high number average molecular weight diblock copolymers which are surface initiated (“grafting from” approach) from either single or multi-wall carbon nanotubes (SWCNTs or MWCNTs respectively). In-situ anionic polymerization results in nanocomposites, exhibiting narrow dispersity indices which are in accordance with anionic polymerization standards, able to self-assemble when studied in bulk. The polymer matrices are diblock copolymers of the PS-b-PI type [PS: polystyrene and PI: poly(isoprene)]. The successful “grafting from” the corresponding CNTs is verified by Raman and Χ-Ray Photoelectron spectroscopy, while the structure/properties relationship of the composites is determined employing High Resolution Transmission Electron Microscopy (HR-TEM). HR-TEM characterization is very important for the successful identification of the MWCNTs as well as for the justified conformation of the polymeric chains grafted from the CNTs.
