N-isopropylacrylamide (NIPAM) and acrylic acid (AA) copolymer microspheres with various composi- tions were prepared by reverse suspension polymerization technique. The microspheres thus prepared were employed as micro-reactors for the deposition of CuS. In this way, sev- eral CuS-P(NIPAM-co-AA) composite microspheres with different surface morphologies were prepared. It was dem- onstrated that the surface structures of the composite mi- crospheres can be tailored to a certain extent by varying the ratio of the two monomer units in the template (microgels) and/or the amount of CuS deposited. It is in prospect that the inherent advantages of microgel templates (the size, compo- sition, charge nature and density, and crosslinking density could be easily controlled) would make the microgel template method extremely useful in the preparation of composite microspheres with different patterned surface structures.
