Synthesis and characterization of polyAMPS brushes.
(a) Synthesis of polyAMPS brushes. The AIBN type initiator monolayer was first self-assembled on the surface on TiNTs. The polyAMPS chains were directly grown from the surface by thermal initiation with the presence of monomers. (b) FTIR spectra were recorded for initiator (grey) and polyAMPS (black) attached TiNTs. PolyAMPS brush was formed by polymerization at 60°C for 6.5 hours. (c) Size distribution curves of free polyAMPS from solution (dash line), titanate nanotubes (dot line) and polyAMPS brushes on titanate nanotubes (solid line) were obtained from dynamic light scattering. Concentrations of the formed suspension solutions are 0.1 g ml−1.
