Material Characterizations of Gr-Based Magnetorheological Elastomer for Possible Sensor Applications: Rheological and Resistivity Properties.

摘要: Considering persistent years, many researchers continuously seek an optimum way to utilize the idea of magnetorheology (MR) materials be practically used for everyday life, particularly concerning resistivity sensing application. The rheology and a graphite (Gr)-based magnetorheological elastomer (Gr-MRE) were experimentally evaluated in present research. Magnetorheological (MRE) samples prepared by adding Gr as new additive during MRE fabrication. effect additional on rheological properties investigated compared with those typical MREs without additive. Morphological aspects Gr-MRE characterized using field emission scanning electron microscopy (FESEM) energy dispersive X-ray spectroscopy (EDX). Rheological under different magnetic fields parallel-plate rheometer. Subsequently, all was measured applied forces fields. From evaluation, two relationship curves resistance (R) (F) (B) established plotted empirical model. It observed from FESEM images that presence fractions arrangement contributes conductivity MRE. also that, addition Gr, such field-dependent modulus can improved, at low strain amplitudes. is demonstrated contribute likely use force detection tactile devices.
