Reasons for Aggregation of Nanoparticles and Solutions

Nanomaterials have special performance 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.
