Abstract: In order to find a new way to improve the dispersion ability of nanometer material,an investigation on preparation of thin film with low surface energy on the surface ofnanometer material by means of plasma polymerization has been done. Some physicalbehaviors and chemical constitution of prepared film as well as the influence of poly-merized film on nanometer material were tested. All the experimental results showedthat this is a possible way to improve the dispersion ability of nanometer materials.

Key words: plasma polymerization, nanometer material
