Experimental study of magnetic field driven properties of magnetic hybrid materials with complex internal interactions
Final Report Abstract
A prominent example of a smart composite within the class of magnetic hybrid materials is an elastomer based on magnetic particles embedded in a polymer matrix. The development of new applications for these composites, particularly in the field of sensors, requires enhanced field-dependent changes in the properties of the materials and a wider range of field control, which can only be achieved by changing the composition of the material. The project continued research into magnetic hybrid materials with complex internal interactions, namely elastic polymers filled with powders of magnetically soft and magnetically hard microparticles. The work was focused on magnetic and magnetorheological characterisation of these composites. Magnetic studies have provided a quantitative assessment of the interactions between the microparticles and the elastic polymer matrix, in particular by testing the local elasticity of the matrix. Moreover, the importance of taking into account the slippage of the magnetic particles in the polymer matrix to reproduce the magnetisation of a real composite was demonstrated. The influence of the cyclic magnetisation of the composite on its magnetic response was also quantitatively evaluated. As part of the study of the anisotropic properties of the magnetorheological effect, it was shown that the measured modulus of elasticity of magnetic elastomers decreases as the angle between an external magnetic field and the applied shear deformation increases. The effect is minimal when the field is nearly perpendicular to the mechanical load, which is the opposite of the effect known for magnetorheological fluids. The project results have not only contributed to the understanding of the physics of magnetic phenomena in elastic magnetic polymer composites, but also serve as a basis for further application-oriented development of intelligent composites with adjustable anisotropy. Due to reasons related to the suspension of the international cooperation in the framework of the DFG-RFFI projects, not all planned collaborative tasks could be carried out according to the proposal.
