Abstract

The invention provides a method for preparing metal surface fullerene film by electrophoresis, including the following steps: (1) pre-treatment is carried out on metal material surface, including oil removing cleaning, acid cleaning and activation on metal material; (2) electrophoresis solution is prepared, fullerene is dispersed in organic solution, ultrasonic oscillation, filtering and reducing are carried out, pH value is regulated to be 8-12; (3) film forming is carried out by adopting fullerene electrophoresis method; (4) heating is carried out. The method of the invention can be used for metal surface modification treatment, especially novel surface coated metal material can be derived by utilizing excellent characteristic of fullerene material, thus obtaining brand new metal product.

Description

technical field [0001] The invention relates to the field of nanotechnology, in particular to a method for preparing a fullerene film by electrophoresis on a metal surface. Background technique [0002] Human beings have discovered and understood carbon for a long time. With the discovery of fullerene carbon clusters, C 60 As new allotropes of carbon, carbon nanotubes have entered people's research field of vision. In 1985, British scientist Kroto and American scientists Curl and Smalley jointly discovered a carbon allotrope similar to a football structure and named it fullerene. Due to the cage structure and excellent properties of fullerene, The study of fullerenes has become a new branch of scientific research. [0003] In the fullerene carbon cluster, C 60 It has a high degree of symmetry, and its cage is surrounded by p electron clouds inside and outside. It is a cage molecule with 60 atoms, and each carbon atom is separated from the surrounding three atoms by sp 2....
