P(AM-co-MAA) copolymer microspheres were prepared by reverse suspension polymer-ization technique, and using acrylamide (AM) and methacrylic acid (MAA) as monomer. A series of polymeric/inorganic P(AM-co-MAA)/Cu2O composite microspheres with patterned surface were prepared by chemical reduction between Cu(Ac)2 in microspheres and glucose in solution, and using P(AM-co-MAA) as the template. The morphology and inorganic dosage of the composite microspheres have been characterized by scanning electron microscopy (SEM), energy dispersive spectrometer (EDS), Fourier transform infrared (FT-IR) and thermogravimetric analyses (TG). It shows that the morphology and inorganic deposition of the composite microspheres were controlled by adjusting concentration of Cu(Ac)2, and C6H12O6, reaction temperature and reaction time. The results indicated that the P(AM-co-MAA)/Cu2O composite microspheres with uniform small Cu2O particles in surface were prepared when the in-situ reaction between 0.20 mol/L Cu(Ac)2 and 0.3 mol/L glucose was carried out at 70℃ for 20 min.

Zeng研究小组［6］采用水热法制得了Cu2O纳米空心球. Chen研究小组［7］报道了以凝胶作为软模板，聚乙烯乙二醇为表面活性剂，在70℃碱性条件下，利用葡萄糖还原CuSO4合成了粒径在200～400 nm具有纳米洞的单晶Cu2O纳米空心球.
