Nickel-zinc ferrite/polyacrylic acid nano-composite material and preparation method thereof
The invention discloses a nickel-zinc ferrite/polyacrylic acid nano-composite material and a preparation method thereof. The nano-composite material is in a core-shell structure and comprises core nickel-zinc ferrite and shell polyacrylic acid; the shell polyacrylic acid coats the nickel-zinc ferrite; and the nano-composite material is represented by Ni0.1-1Zn0.1-1Fe1-3O2-6/PAA. The preparation method of the nano-composite material mainly comprises the following steps: (1) weighing zinc sulfate, ferrous sulfate and nickel sulfate to prepare a metal salt solution, adding the metal salt solution into an ammonium oxalate solution; (2) adjusting the pH of the mixed solution, and separating and drying the mixed solution to obtain a ferrite precursor; (3) burning the ferrite precursor to obtain the nickel-zinc ferrite; and (4) mixing and reacting the nickel-zinc ferrite and acrylic acid, and separating and drying the mixture to obtain the nickel-zinc ferrite/polyacrylic acid nano-composite material. The nickel-zinc ferrite/polyacrylic acid nano-composite material has the advantages of low specific saturated magnetic field intensity, relatively low coercive force and relatively high soft magnetic property; and the preparation method disclosed by the invention is simple, feasible and low in cost.
