The zinc oxide doped titanium dioxide composites （ZnO/TiO2 ） were synthesized by hydrolysis method. Under different microwave conditions, the antibacterial effects of the prepared composites were tested to find the optimum process conditions of the antibacterial test including the mass ratio of the composites and eiderdown, radiation power, radiation temperature and radiation time. Meanwhile, the composite materials was recycled and the antibacterial effects of the recycled composites were studied. The results revealed that the optimum antibacterial conditions were as follows： the mass ratio of ZnO/TiO2 composites and eiderdown 3： 1, radiation power 400 W, radiation temperature 47 ℃ , radiation time 1 min. And the highest inhibition rate was 78.89%. The inhibition rate of the prepared composites after the first recycling was 64.71%. However, the ZnO/TiO2 composites can be recycled at least two times.
