PHOTOACTUATING NANOCOMPOSITES BASED ON BLOCK COPOLYMERS AND COVALENTLY MODIFIED MULTIWALLED CARBON NANOTUBES
Original language description
Since their discovery, carbon nanotubes (CNT) have attracted particular attention for their unique structural, mechanical and electrical properties. However, thank to strong van der Waals interactions, CNT tend to aggregate, what results in not uniform CNT dispersion limiting their potential applications. Functionalization of CNT with long molecules and polymer chains enables suppressing the interactions between CNT and their aggregation. In this work, Nanocyl multiwall carbon nanotubes (MWCNT) were covalently modified in order to improve their dispersability in various thermoplastic elastomers. The modified MWCNT were characterized by various techniques, such as SEM, TEM, TGA, and FTIR. The composite films were prepared by casting of toluene solutioncontaining styrene-isoprene-styrene (SIS) block copolymer and various amount of MWCNT. The modification significantly improved dispersion of carbon nanotubes in SIS. The best dispersion was observed when 0.1 wt. % of MWCNT-PS was used. Th
