A facile method to synthesize magnetic polymer nanospheres with multifunctional groups
Source abstract
Abstract
Abstract Magnetic poly(styrene methyl methacrylate)/Fe 3 O 4 nanospheres with ester groups were prepared by a modified one-step mini-emulsion polymerization in the presence of Fe 3 O 4 ferrofluids. The effects of monomer dose, surfactant content, ferrofluid concentration and initiator content on the particle characteristics such as the size, morphology and magnetic properties were investigated by Fourier-transform infrared spectroscopy, transmission electron microscopy, thermogravimetric analysis and vibrating sample magnetometer. The results indicated that magnetic nanospheres were superparamagnetic with high saturation magnetization of 51.0 emu/g and corresponding magnetite content of 61.5 wt%. Subsequently, magnetic nanospheres with carboxyl and amino groups were also obtained by hydrolysis and ammonolysis reaction. These magnetic nanospheres with multifunctional groups have biomedical applications.
