To increase the hydrophilicity and
biocompatibility of carbon nanotubes (CNTs) Li
Yan et al.covalently grafted guar gum (GG)
on the surfaces of multiwall carbon nanotube
(MWCNT) to obtain GG–MWCNT composite
along with iron nanoparticles bounded on the
GG–MWCNT to prepare the magnetic GG–
MWCNT–Fe3O4. Resultant nanocomposites
were analyzed by FTIR, TGA/DTA, TEM, UV–
vis spectroscopy and X-ray diffraction. Guar
gum-g-epichlorohydrin was investigated by T.
Hongbo et al.by reacting epichlohydrin with
guar gum in the alkaline condition .
