摘要：Monodisperse PS beads were prepared by miroemulsion polymerization method. Styrene monomer (0.99%), potassium persulfate (0.44%), and sodium dodecyl sulfonate (0.27%) was used as precursor, initiator, and surface active agent, respectively, and then used a novel and simple electroless plating method coating nickel on PS beads substrate by pd-free activation process (nickel acetate 2.27%, sodium borohydrate 2.27%, and sodium hypophosphite 2.50%), lastly, the mixture samples were annealed at 500 degrees C for 5 h to obtain nanoporous nickel. SEM, EDS, XRD was used to characterize these samples. N-2 sorption was used to analyses of pore structure.The results indicate that pure PS beads show 120-150 nm of particle size, while the aperture of the nanoporous nickel is about 100-130 nm of particle size, the shell thickness is about 15-20 nm, and the specific surface areas is 161.69 m(2) g(-1).
