Electroless plating of nickel on the surface of polyaniline microtubules and electromagnetic property study

Polyaniline microtubules were prepared by using in situ doping method and polyaniline microtubule/Ni composites by electroless plating method. The sample before and after coating was checked via X-ray diffraction and energy dispersive spectrometry. The effect on polyaniline microtubule fundamental chain in the process of electroless nickel plating included catalysis by SnCl₂, activation by PdCl₂ and temperature of electroless plating solution. The electromagnetic property was studied to find that Ni has been deposited on the surface of polyaniline microtubules orderly and tightly, the process of catalysis by SnCl₂ and activation by PdCl₂ have little effect, while temperature of electroless plating solution has large effect on polyaniline microtubule fundamental chain. The higher the temperature was, the more the polyaniline was reduced, and the bone chain was changed least at 35 °C.
