Water-dispersible polymer/Pd/Ni hybrid magnetic nanofibers

Reported are the preparation and characterization of Pd/Ni nanoparticles in the core of water-dispersible nanotubes of a triblock copolymer. The preparation involves first the preparation of the triblock nanotubes and then the production of Pd nanoparticles inside the nanotube cores. Ni is introduced in the final step by electroless deposition using Pd as the catalyst. The challenges facing each reaction step are discussed.
