Study of filler microstructure in magnetic soft composites

Abstract

Electron and atomic force microscopy were used for the study of magnetoactive filler surface microstructure in a magnetorheological composite. The particles redistribution phenomena of filler aggregates on the surface of elastomers under the action of a small external applied constant magnetic field are visualized. A model is proposed for the interaction of a magnetoactive filler with an elastomeric matrix of the composite, which explains the observed experimental results.

“…In the joint studies of Institute of Applied Mechanics, Mechanical Engineering Research Institute of the Russian Academy Sciences and State Scientific Center State Research Institute for Chemical Technologies of Organoelement Compounds with the atomic force microscopy help, the magnetic filler restructuring that occurs in such composites under the external magnetic field influence was directly visualized. Further research was carried out on the surface structure of a similar magnetoactive composite using scanning electron microscopy (SEM) and atomic force microscopy (AFM) [24][25]. The results obtained make it possible to better understand the observed unique effects characteristic for such magnetoactive elastomers.…”
