Preparation and Stduy on the Structure of Surface-Modified MsS Nanoparticles
Surface-modified MnS nanoparticles were synthesized in mixed solvent of water-ethanol by the reaction of MnCl2•2H2O, Na2S•9H2O and surface modification agent dialkyldithiophosphate(DDP). The structure of surface-modified MnS nanoparticles was investigated by XPS,FTIR,TGA, XRD, TEM and HREM. The results show that the DDP-capped MnS nanoparticle consists of a layer of DDP molecules and MnS nanoparticles core. The diameter of DDP-capped MnS nanoparticles is 510 nm. The crystalline structure of inorganic MnS nanoparticle core is γ-MnS. Meanwhile, Surface-modified MnS nanoparticles have better chemical stability and thermostability. They are also well dispersed in organic solvents such as trichloromethane, benzene and in liquid paraffin.
