超细金属-高分子复合纳米粒子的制备与表征
Preparation and Characterization of Ultrafine Metal/Polymer Composite Nanospheres
【摘要】 成功地使用了种子乳液聚合方法制备出粒径为30 0nm左右的苯乙烯 (Styrene) /丙烯酸 (Acrylicacid)共聚小球。首次报道通过紫外射线辐照方法使吸附在苯乙烯 /丙烯酸共聚小球表面的钴离子还原 ,进而使高分子球外表面包覆一层超细金属Co粒子。采用XRD、TEM等对其复合粒子进行了表征。
【Abstract】 Copolymer nanospheres of styrene/acrylic acid were prepared successfully by seeded emulsion polymerization.Cobalt ions absorbed on the surface of copolymer nanospheres were reduced by ultraviolet irradiation and cobalt/copolymer composite nanospheres were obtained.These nanospheres were characterized by XRD and TEM.The effects on the preparation of composite nanospheres were also studied in detail.
