纳米颗粒团聚的原因及解决措施

Reasons for Aggregation of Nanoparticles and Solutions

纳米材料有常规材料所不具备的特殊性能,广泛应用于各个领域。由于纳米颗粒表面的高能性、不饱和性、不稳定性,导致纳米颗粒团聚,限制了纳米材料的应用领域和效果。介绍了纳米颗粒团聚的主要原因,依据物理原理和化学原理阐述了解决团聚的措施,提出纳米颗粒分散技术的发展前景。

Nanomaterials have special perforrqance which conventional materials do not have, and they are widely used in various fields. Because the high performance, non-saturability and unstability of the surface of nanoparticles they lead to the aggregation of nanoparticles, limit the application and effect of nanomaterials. This paper introduces the main reasons for the aggregation of nanoparticles, describes measures to solve the aggregation based on principles of physics and chemistry, and puts forward the prospect of the dispersion technology of nanoparticles.
