Fluorination of multi-layered carbon nanomaterials
Yazami and Hamwi have fluorinated multiwall carbon nanotubes by treating with fluorine gas at 375°C for more than 4 hours. The partially fluorinated MWCNT enables partial conductivity and can provide good performance of lithium batteries at high discharge rates. (RDC 11/19/2010)

Functionalization of multiwalled carbon nanotubes with amphiphilic poly(aspartic acid)
(772–777) AIChE Journal 57 #3 (2011)
Ji, Yang and Feng of the Beijing University of Chemical Technology, China synthesized the amphiphilic polymer (PASP-C16) by thermal condensation and aminolysis by hexadecylamine, followed by hydrolysis of the remaining succinimide units in the polymer backbone. The functionalization of MWNTs was achieved by physical adsorption of the biopolymer onto the surfaces of MWNTs. The interaction of hexadecyl chains of PASP-C16 with the wall of MWNTs is the major interaction between PASP-C16 and MWNTs, and MWNTs were covered by the poly(aspatic acid) backbone. (RDC 2/10/2011)
