Particle Size Influence on the Effective Permeability of Composite Materials

Abstract

The energy method, which estimates the effective permeability of composite material is proposed. We approximate the effective static magnetic permeability by energy method and Maxwell-Garnett method for spherical particles dispersing system. Considering the effect of the interface layer between the medium and the particle, we study the nanoparticles embedded in a medium exactly. The interface layer property plays a significant factor for the effective permeability of the composite material in which nano-sized particles embedded.

The effect of spherical filled particles on the energy storage density of composite materials

“…Therefore, the value of the permittivity is not always better, and a moderate permittivity is beneficial to obtain higher energy storage densities. This conclusion can be illustrated in Figure 1 [9] .The shaded part of the figure indicates the energy storage density. As shown in Figure 1, in comparison between the two materials, material A has a higher dielectric constant because of the low electric field in the environment, and premature saturation of the polarization intensity of material A.…”

Effects of Pressure from High‐Pressure Homogenization on the Performance of Soybean Flour Based‐Adhesive

“…Therefore, uneven size distribution means an unstable bonding performance. [ 28 ] Because the particle size of SF adhesive was large and uneven (80.7–138.3 µm, Figure A and Table 1 ), the adhesive performance, according the above discussion, is poor and unstable. After introducing the TGA cross‐linker, the particle size range of adhesive B was reduced to 50.5–75.5 µm.…”
