| Abstract: | Magnetic polymer particles with hydro groups on the surface were synthesized by disperse polymerization in the presence of magnetic fluid,then a novel kind of green magnetic polymer particles (PSFePc(COOH) 3) was obtained by bonding the magnetic polymer particles with phthlaocyanine.The structure and properties of PSFePc\|(COOH) 3 particles were identified by infrared spectroscopy,element analysis and scanning electron microscopy etc. It was found that:(1) the particle size is in the range of 10～100?μm and the grafting ratio of phthlaocyanine is about 4 8%;(2) the particles show a good magnetic response in magnetic field,it takes about 2?h in natural sedimentation to reach a transmittance of 95%,while the same separation results under a magnetic field of 0 42T only need about 10?min;(3) the particles have photoconductivity.It maybe helpful to find a new method for detecting the interaction between bio\|active molecules by using photoconductivity measurements. |
