This work successfully prepared nanohybrids by
in situ atom transfer radical polymerization (
ATRP)
of styrene from titanate nanotubes (TNTs). Fourier-transform infrared
(FT-IR), pronton nuclear magnetic resonance spectroscopy (
1H
NMR), and thermal gravimetric analysis (TGA) were used to verify the
successful graft of polystyrene (PS) chains from TNTs. Transmission
electron microscopy (TEM) displayed that the obtained PS-
g-TNTs
nanohybrids had a core-shell structure of TNT core and PS shell. The
grafted PS content was well controlled and increased with increasing of
the monomer/initiator ratio. Further copolymerization of
tert-butyl acrylate (
tBA) from the surface of PS-
g-TNTs was studied, illustrating the “l(fā)iving” characteristics of the surface-induced
ATRP method used in this work.
