Abstract: The NiZn ferrite and multiwalled nanotubes were mixed by the weight ratio of 1:1, then the mixture were incorporated into the thermoplastic natural rubber nanocomposite by melt blending process. The physical properties: thermal stability, magnetic properties, dynamic mechanical properties, and morphology of the obtained composites were investigated in the aspect of filler loadings effects. It was found that both NiZn ferrite and multiwalled nanotubes are well dispersed in the thermoplastic natural rubber matrix. The thermogravimetric analysis and vibrating sample magnetometer results indicate that the filler loading has improved the thermal stability and the magnetic properties of the composite. The dynamic mechanical test shows that the highest storage modulus was achieved by 8 wt% filler. Any further increment of the filler content leads to the formation of agglomerate, hence, affecting the dynamic mechanical properties.
