| Abstract: | Core-shell multifunctional composite spheres consisting of Fe304-polyaniline （PANi） shell and polystyrene （PS） core were fabricated using templates of core-shell-structured sulfonated PS spheres. Dissolved with solvent, PS cores were removed from the core-shell composite spheres and hollow FeaO4-PANi spheres were obtained. The cavity size of the hollow spheres was uniformly approximate to 190 nm and the shell thickness was 30 nm. The cavity size and the shell thickness can be controlled by varying the sulfonation time of the PS templates. The thus prepared spheres present good conductivity and super-paramagnetic. The turbidity removal efficiency of artificial waste water removed by hollow Fe304 and hollow Fe304- PANi spheres were 84.2% and 86.9% respectively. |
