MWCNTs polystyrene-grafted

Polymer-linked MWCNT nanocomposites were prepared by reversible addition fragmentation chain transfer (RAFT). The RAFT reagent was successfully grafted on to the surface of MWCNTs and PS chains were grafted from MWCNTs via RAFT polymerization [192], By covalently linking acyl chloride functions of functionalized MWCNTs with living polystyryllithium, Huang et al. succeeded in the preparation of polystyrene-functionalized MWCNTs (Scheme 1.32) [193],... 

Another kind of amphiphilic block copolymer-grafted MWCNTs was prepared by sequential ATRP of styrene and fBA using CNT-Br-1 as the initiator, followed by hydrolysis of the poly(tert-butyl acrylate) (P BA) block into PAA," as shown in Figure 5.12. The polymer amount of the second block can also be adjusted by the feed ratio of fBA to polystyrene (PS)-grafted MWCNTs, demonstrating the living characteristics of the block copolymerization. The core-shell amphiphilic nano-object can self-organize into a film at the interface of chloroform and water. 

Shaffer and Koziol followed the same route to graft polystyrene (PS) onto the walls of MWCNTs, synthesized by a CVD technique...
