摘　　要：以丙烯酰胺(AM)和2–丙烯酰胺基–2–甲基丙磺酸(AMPS)为单体,氯化钯为钯源,在不加任何还原剂和引发剂的情况下,采用微波辐照法合成纳米钯/P(AM–AMPS)复合材料。研究了溶液的酸碱度、单体的摩尔比、微波辐照时间等因素对反应体系的影响,结果表明:p H为7.0左右,n(AM)∶n(AMPS)=4,微波辐照时间45 min时聚合物体系的反应程度最大。利用透射电镜(TEM)、扫描电镜(SEM)观察纳米钯复合材料,结果显示:聚合物呈网状结构,具有很好的包覆性;钯粒子的粒径约为20 nm。The nano-Pd/P（AM-AMPS） composites were prepared by microwave radiation method using acrylamide（AM） and 2-acrylamido-2-methylpropanesulfonic acid（AMPS） as monomers and palladium chloride as Pd source in the absence of any reducing agent and initiator. The influence of the factors including acidity-alkalinity of solutions, molar ratio of monomers, microwave radiation time etc. on reaction system was studied. The results show that the reaction extent is maximum when the p H value is approximately 7.0, n（AM） ： n（AMPS）=4 ：1, microwave radiation time is 45 min. The nano-Pd composites were observed by using transmission electron microscope（TEM） and scanning electron microscope（SEM）. The results show that the polymer possesses network structure and excellent coating performance, and the particle size of Pd particle is about 20 nm.
