Abstract:
In the present study the preparation and characterisation of rubber ferrite
composites containing nickel ferrite and gamma ferric oxide have been dealt with.Synthetic rubbers viz. ethylene propylene diene rubber and neoprene rubber were used
for the incorporation of nickel ferrite and gamma ferric oxide for the synthesis of
RFCs. Incorporation of ferrites were carried out according to a specific recipe for
various loadings of the magnetic fillers. The ferrites used for the preparation of RFCs
were synthesised using sol-gel method and structural characterisation was carried out.
Experimental techniques like X-ray diffraction, Transmission electron microscopy and
other analytical techniques were used for this. Precharaterised ferrites were then
incorporated at different loading into rubber according to conventional mixing
methods. The cure characteristics, mechanical, dielectric, magnetic and microwave
properties of these composites were evaluated. The effect of carbon black on these
properties of RFCs were carried out.
