随着超导、强制冷系统和大功率电源等技术的快速发展
高达十几个特斯拉的稳态磁场和几十个特斯拉的脉冲磁场得以实现
为研究强磁场下的高分子物理化学行为提供了条件。本文首先简要介绍了碳纳米管在磁场中的取向机理
接着详细综述了磁场作用对含磁性组分(如铁的氧化物
Ni和Co单质及其氧化物
液晶等)或不含磁性组分的高分子/碳纳米管复合材料取向及力学、导电、导热及光学等性能的影响
最后对强磁场下高分子物理化学的研究进行了展望。
With the rapid development of superconducting technology
forced cooling system and large power supply
steady high magnetic field with a dozen of Tesla and pulsed magnetic field with tens of Tesla can be achieved under laboratory conditions
which enables us to investigate the magnetic response of polymers and their composites. In this review
we focus on the orientation of carbon nanotubes and the properties of their polymeric composites including mechanical
thermal
electrical
and photoresponsive properties
with or without magnetic components such as ferromagnetic iron oxides (FeO
x
)
nickel
cobalt and their oxides
liquid crystal. We also present some main difficulties and give some prospects for research interests in the near future.
