NANOCOMPOSITES BASED ON STYRENE-ISOPRENE-STYRENE BLOCK COPOLYMERS AND COVALENTLY MODIFIED CARBON NANOTUBES
Original language description
Multiwall carbon nanotubes (MWCNT) were covalently modified in order to achieve better dispersion in a block copolymer matrix. Surface of MWCNT was modified either a) by polymerization of styrene from MWCNT surface (MWCNT-PS), or b) by covalent bonding of cholesteryl groups (MWCNT-chol). In both cases, MWCNT surface was first modified by 4-(2-hydroxyethyl)nitrobenzene to introduce hydroxyl groups onto MWCNT surface (MWCNT-OH). MWCNT-PS were prepared by reaction of MWCNT-OH with 2-bromopropionyl bromideand subsequent atom transfer radical polymerization of styrene from the surface of MWCNT by ATRP using CuBr/PMDETA as a catalytic system. MWCNT-chol were prepared by esterification of MWCNT-OH by reaction with cholesteryl chloroformate. The modified MWCNT were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermal gravimetric analyses (TGA), and Fourier transmission infrared spectroscopy (FTIR). The composite films were prepared by casting of
