“…Multifunctional polymer nanocomposite containing inorganic particles can be tailored to exhibit both the electrical and magnetic properties. There is an increased demand for flexible magnetoelectric composite by the incorporation of relatively small amount (1–15 phr) of conductive fillers to convert the polymeric material into a semi‐conductive one . The advantages of using such polymer composite is its lightweight, low cost, high strength, elasticity, toughness, and can be easily tuned to desired shape through different techniques.…”

Nanocomposites of ethylene vinyl acetate (EVA) containing iron oxide nanoparticles (IONPs) were prepared by open mill‐mixing technique. The effect of loading of IONPs in EVA was characterized by Fourier transform infrared (FTIR), X‐ray diffraction (XRD), transmission electron micrograph (TEM), and dynamic mechanical analysis (DMA). The FTIR spectra ascertain the intermolecular interaction between the polymer and IONPs. TEM and XRD studies revealed the structurally ordered arrangement of nanoparticles within the polymer matrix. DMA showed an increase in storage modulus and lesser damping characteristics of composite with the increase in loading of nanoparticles, whereas these properties decreased significantly with increase in temperature. The glass transition temperature shifted toward higher temperature with the increase in content of IONPs. Magnetic properties of the nanocomposites were investigated using vibrating sample magnetometer at room temperature. The saturation of magnetization was progressively increased with the increase in content of nanoparticles. The electrical conductivity, dielectric constant, and dielectric loss of the composite were found to be increased with the increase in volume fraction of nanoparticles. The polymer–filler interaction was also determined from the swelling studies. POLYM. COMPOS., 35:1989–1996, 2014. © 2014 Society of Plastics Engineers

Magnetorheological elastomers (MREs) based on waste nickel zinc ferrite and natural rubber were prepared. The amount of waste nickel zinc ferrite was varied at five levels (20, 40, 60, 80, and 100 phr) to assess the optimum amount of waste nickel zinc ferrite content for highest dynamic mechanical and tensile performance. Curing characteristics of the MREs were determined by moving disk rheometer (MDR 2000), and thermal properties were evaluated by thermogravimetric analysis (TGA). Tan δ was measured through parallel and plate rheometer over a frequency range of 0.1–100 Hz and a strain amplitude range of 0.1–6%. Tensile properties were measured with a universal tensile tester. The results revealed that tan δ, tensile properties, and thermal stability of the MREs increased with increase of waste nickel zinc ferrite contents. Anisotropic MREs, which had chain-like columnar structures of magnetic particles in the matrix as a consequence of an applied magnetic field during curing, were found to produce higher dynamic mechanical performance compared with isotropic MREs cured in the absence of a magnetic field.
