| 摘 要： | 采用蒙特卡洛模拟方法研究了在外磁场作用下磁性纳米粒子/高分子刷组成的共混体系的统计构象性质.共混体系受限于两平行板之间,高分子刷—端随机嫁接在乎行板上,另一端自由生长,高分子刷与高分子刷之间以及磁性纳米粒子与磁性纳米粒子之间存在相互排斥作用,而高分子刷和磁性纳米粒子之间存在相互吸引作用,所施加的磁场方向与两平行板垂直....

| Abstract: | The statistical properties of systems composed of polymer brushes and magnetic nanoparticles placed in a magnetic field are studied by means of Monte Carlo simulation.The direction of the magnetic field is perpendicular to the substrate plane.Polymer brushes and magnetic nanoparticles are attractive to each other.The average heights of polymer brushes depend not only on the strength of applied magnetic field,but also on the brush grafting density,chain length and magnetic nanoparticle concentration.The appl... |
