| Abstract: |
| In order to improve the dispersion property and the compatibility with organic medium of ultrafine nickel powders, ultrafine nickel powders were encapsulated with surfactants. The effects of the types of surfactants, pH value and solvent on the lypohydrophilic character, dispersion property and anti acid corrosion performance of particles encapsulated were studied. The experiments show that DBSA is an ermnent encapsulation reagent. The effects of pH value and solvent on the properties of ultrafine Ni-DBSA composite powders were investigated. The structure of composite particles on the surface was identified with FTIR and the morphology of them was observed using TEM. The results show that Ni-DBSA composite powders have very good core-shell structure; furthermore, the surface of Ni particles is replaced completely by DBSA molecule when the pH value is 9 and non-ion water is adopted. |
