Theoretical and experimental investigation of the particle size distribution and magnetic properties of the PP + FE₃O₄ nanocomposites

Abstract

A detailed study of the dispersion of magnetite (Fe3O4) nanoparticles in the polypropylene (PP) matrix, the degree of coagulation, and the dependence of magnetic properties of PP + Fe3O4 nanocomposites on the size of nanoparticles is reported. The size distribution of nanoparticles in polymer matrix and morphology of the nanocomposites were studied by the means of scanning electron microscope (JEOL JSM-7600 F) and atomic force microscopy (NT-MDT). It was found that when the Fe3O4 nanoparticles are introduced into the PP matrix, their coagulation takes place. The increase in the size of the Fe3O4 nanoparticles depends on their volume content in the polymer matrix, the viscosity of polymer, mixing time, and so on. The magnetic properties of PP + Fe3O4 nanocomposites were experimentally and theoretically studied. It was found that the magnetic hysteresis parameters of the nanocomposites directly depend on the size and concentration of the Fe3O4 nanoparticles in the matrix. Theoretical calculations were compared with experimental results obtained from M( H) measurements. Discrepancy between theoretical and experimental magnetic values have been explained.

Synthesis, characterization, magnetoelectric properties and gas sensing application of Poly(anthranilic acid-co-indole)/ magnetite nanocomposites

“…6 Magnetite (Fe 3 O 4 ) is one of the most extensively studied nanomaterials due to its higher chemical stability, biocompatibility, high dielectric constant, magnetic susceptibility, high saturation magnetisation, easy to synthesis and inexpensive. [7][8][9][10] The distinctive electrical and magnetic properties of Fe 3 O 4 are due to the transfer of ions from Fe 2+ ions to Fe 3+ ions. In search of advanced conjugated conducting polymeric materials, copolymerization of indole with anthranilic acid monomers in the presence of Fe 3 O 4 nanoparticles exhibits interesting properties which have not been much explored earlier.…”

Effect of Hollow Glass Microspheres with Different Contents and Types on Properties of Polypropylene Composites

“…Although pure PP can be used as thermal insulation and sound insulation materials, the mechanical properties are not sufficiently high for many applications. [20][21][22] In this regard, PP is usually filled with rigid inorganic particles, such as talc, [20] glass microspheres [23] or calcium carbonate, [24] fibers, [25][26][27] wood powder, [28,29] and rubber particles [30] to further enhance the mechanical properties. After the addition of hemp wood fibers to polypropylene, the modulus and water absorption of the composites were enhanced, without mentioning the analysis of the density.…”
