ABSTRACT: Long chain phosphate esters
bearing at least one or two aryl groups have been synthesized and used for the
preparation of stable multi-walled carbon nanotube (MWCNT) hybrids. The non-covalent interaction
ester/MWCNT has been investigated by several techniques (SEM, UV-vis, 31P-NMR, RAMAN). The used phosphate
ester derivatives demonstrated
the ability to produce an excellent dispersion of MWCNT in CHCl3. The obtained dispersions showed a
great stability from one to at least three weeks in the range of concentration
considered. Thermal analysis showed an increase in the decomposition temperature for
the hybrids with respect to pristine MWCNT.
