【摘要】 本论文采用辐射聚合方法在粒子表面引入接枝聚合物,以改善粒子在聚合物基体中的分散情况及调节界面作用,并选用溶液共混及原位聚合方法制备了金属纳米粒子/聚合物复合材料。研究了辐射气氛对接枝率的影响,研究了接枝粒子在溶液中分散状况,从纳米粒子与聚合物之间相互作用的角度,初步分析了该复合材料的磁性能。更多还原

【Abstract】 To tailor the interracial interaction in magnetic metal nanoparticles filled polymer composites, surfaces of iron, cobalt and nickel nanoparticles were grafted by irradiation polymerization. In the current report, effects of grafting conditions, including irradiation atmosphere, irradiation dose and monomer concentration, on the grafting reaction are presented. The metal/polymer nanocomposites prepared either by solution mixing or in-site polymerization show that their magnetic properties are a function of the interfacial interaction and the dispersing state of the nanoparticles.更多还原
