Abstract： |
The present invention relates to a kind of composite material with capacitance and inductance performance, and belongs to the field of electronic composite material technology. The composite material is ternary composite material Ni0.3Zn0.7Fe1.95O4-Ni-PVDF and ternary composite material Ba3Co2Fe23O41-Ni-PVDF. It is prepared through mixing ferrite, metal nickel grain and polyvinylidene fluoride, and molding the mixture at temperature of 180-220 deg C and pressure of 10-15 MPa for 20 min. The Ni0.3Zn0.7Fe1.95O4-Ni-PVDF system has initial magnetic permeability of about 30 in the pressure below 10 MHz and dielectric constant at 1 KHz below up to about 200; and the Ba3Co2Fe23O41-Ni-PVDF system has initial magnetic permeability of about 4.0 in the pressure below 500 MHz and dielectric constant at 10 MHz below up to about 130. The composite material possesses unique double seepage structure, and has low preparation temperature, simple preparation process and excellent industrial application foreground. |
