Functional nanoparticles (NPs), Fe3O4@SiO2-PMEMA,
were prepared via surface initiated reversible addition-fragmentation chain
transfer (RAFT) polymerization, using catechol-based biomimetic RAFT agent
incorporating a trithiocarbonate unit and 2-N-morpholinoethyl
methacrylate (MEMA) as the monomer. Poly(2-N-morpholinoethyl
methacrylate) (PMEMA) were synthesized on biomimetic RAFT agent functionalized
Fe3O4@SiO2 NPs surface. The prepared NPs were
characterized at the different modification stages using attenuated total reflectance-Fourier
transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS),
X-ray diffraction (XRD), thermogravimetric analysis (TGA) and transmission
electron microscope (TEM). The magnetic properties of NPs were also determined
by vibrating sample magnetometer (VSM).
