Soluble Nylon-Functionalized Carbon Nanotubes from Anionic Ring-Opening Polymerization from Nanotube Surface

摘要

The preparation of polymeric nanocomposites filled with single-walled carbon nanotubes (SWNTs) generally requires the nanotubes being homogeneously dispersed and compatible with the polymer matrix.An effective approach for these requirements is to functionalize the nanotubes with polymers that are identical or structurally similar to the matrix polymers.Among the widely pursued functionalization strategies is the "grafting-from" method,in which monomers or initiators are first attached to the nanotubes to serve as starting points for propagation.The grafting-from strategy is generally similar to in situ polymerization,but in a more controlled fashion.
