| Abstract: | The Fe_3O_4-urushiol formaldehyde polymer(PUF) magnetic microspheres was synthesized via suspension condensation polymerization.The Fe_3O_4 nanoparticles primarily prepared by coprecipitation.The microspheres have been characterized by XRD,TEM and TG etc..The preliminary results show that the microspheres are core-shell structure with Fe_3O_4 as the magnetic core and PUF as the shell.The size of the microspheres is about 1 mm.The microspheres possess high stability to heat and solvent. |
