TEM images. a Pristine multiwalled carbon nanotubes (MWCNTs). b The mechanical mixture of carbon nanotubes with the poly2,7-NAF.DM. The MWCNTs/polymer ratio was 1:10 (sample 5 in Table 1). c Carbon nanotubes with chemisorbed layer of the poly2,7-NAF.DM. Chemisorption was realized via in situ grafted polymerization of the monomer on the nanotubes surface functionalized with vinyl trialkoxysilane. The MWCNTs/poly2,7-NAF.DM ratio was 1:40 (sample 7 in Table 1)
