Surfactants KH560,KH550,F127 and CTAB were selected to modify the surface of the silicon nanoparticles.The effect of surfactants on the dispersion stability of Si in solvent DMSO and polymer solution of PAN/DMSO was researched,and the mechanism was revealed by examing the particle size and Zeta potential of Si in DMSO as well as the aggregation of Si in Si/PAN/DMSO mixture.Results showed that the dispersion stability of Si in DMSO and polymer solution of DMSO/PAN could be improved to some extent by any surfactant mentioned above.Among them,F127 was the optimal choice for possessing the highest steric hindrance,the best dispersion effect and could meet the technical requirements of deaeration for polymerization liquid.
