Introduction Nano-material is an important research field of nano-science and developed in the mid-80s.
Nano-material was known as “the most promising materials in the twenty-first century” [1-2].
Its properties is not only differred from atoms, but also defferred from bulk materials[3].
At the same time, surface active agent can hinder the aggregation of nano-materials.
