Abstract:

Composite hollow spheres with IPN structure were synthesized by swelling polymerization against a PS hollow sphere. After modification, carboxyl group was introduced to the shell. The polymeric gel can induce a favorable growth of various components forming composite/polymer hollow spheres without the removal of any template. Various functional composite hollow spheres such as silica/polymer, titania/polymer and palladium/polymer were prepared by this method. After removing polymer, silica and titania hollow spheres can be obtained.

Key words: Template synthesis, Swelling polymerization, Composite, Hollow sphere
