alization of multiwalled carbon nanotubes with various molecu-
lar-mass poly(L-lactic acid). J Phys Chem B. 2005;109(47):
A good complexing ligand, 1,10-phenanthroline, may be
tethered to MWCNT by either ether or ester linkages. The
thermal stability of these adducts as determined by ther-
mogravimetry is sufficient to permit their use in a variety of
applications including robust heterogeneous catalyst sys-
tems that may be recycled repeatedly. While the ether-
linked adduct will likely be the most durable (less sensitive
to hydrolysis, etc.), both adducts display good thermal
stability with extrapolated onset temperature for degrada-
tion of [400 °C. The mode of degradation is different for
the two adducts. The ether-linked adduct apparently
undergoes degradation via scission of the attachment to the
MWCNT while the ester-linked adduct degradation reflects
decomposition of the ligand.
