英文摘要：

Silver-poly（4-vinylpyridine） （Ag-P4VP） hybrid microgels were synthesized by 7-irradiation and surfaetant-free emulsion polymerization in a single step. The effects of dose rate and the concentrations of isopropanol,silver ion, N, N′-methyienebisaerylamide （Bis） and 4-vinylpyridine （4-VP） on the hybrid mierogels were studied in detail via transmission electron microscopy （ TEM ）, powder X-ray diffraction （XRD） or dynamie light scattering （DIS）. The results indicated that the size of Ag nanopartieles in the hybrid mierogels increased with the increase of Ag^＋ or Bis concentration and with the decrease of dose rate or isopropanol concentration. When the dose rate was decreased, the phase state of Ag nanopartieles was gradually transformed from amorphous state to cubic crystalline state. Although the variety of the P4VP mierogels＇ size was more complex, it could also be easily adjusted by the above-mentioned conditions.
