Rheological properties of carbon nanotubes-reinforced magnetorheological elastomer

Magnetorheology: a review

“…314 Indeed, Poojary et al 314 found an optimum CNT concentration below which G 0 increased and tan d decreased. Similar observations were reported by Aziz et al 312 synthesizing MREs with pristine, carboxylated and hydroxylated multiwalled CNTs as additives below the aforementioned optimum concentration. Finally, Shabdin et al 308 investigated the rheology and resistivity of graphite based MREs.…”

“…Lee et al 319 described the preparation of MREs containing g-Fe 2 O 3 rod-shaped hard magnetic particles added to CIP to enhance the MR effect of MREs. Also, Borin et al 311 investigated the mechanical properties of MREs prepared by 265 CIP/CNT RTV silicone rubber B15 000/B30 000 : 40 Sphere/fibers Li and Zhang 305 CIP Silicone rubber B50 000/B5000 Spheres Nayak et al 306 CIP/carbon black RTV silicone elastomer B5000/unknown Sphere/unknown Kwon et al 307 CIP/maghemite Natural rubber B5000/B500:unknown Sphere/rod Shabdin et al 308 CIP/graphite Silicone rubber B6000/B16 000 Sphere/unknown Lu et al 309 CIP/carbon black Natural rubber B3200/unknown Sphere/unknown Fan et al 310 CIP/carbon black Natural rubber B3000/B100 Sphere/unknown Borin et al 311 CIP/NdFeB PDMS B5000/B35000 Spheres Aziz et al 312 CIP/MWCNT Natural rubber B6000/B10 000 : 10 Sphere/fibers Aziz et al 313 CIP/MWCNT Natural rubber B6000/B10 000 : 20 Sphere/fibers Poojary et al 314 CIP/CNT RTV silicone rubber B5000/B10 000 : 20 Sphere/fibers Sorokin et al 315 Fe/magnetite Silicon rubber 55 000/35 Spheres Aloui and Klüppel 316 CIP/iron oxide Styrene-butadiene rubber 3500/15 Spheres/irregular von Lockette et al 317 Iron/iron RTV silicone rubber 40 000/10 000 Unknown mixing soft and hard magnetic particles. Although the MR response is mainly governed by the (easily magnetizable) soft particles, values of E 0 and tan d in the on-state were larger when hard particles were pre-magnetized (see Fig.…”

Magnetorheological Elastomers: Materials and Applications

“…Apart from increasing the plasticity and fluidity of the matrix, the additives can average the distribution of the internal stress in the materials, which makes a stable material property for MR elastomer materials [1,58]. The other additives include but are not limited to carbon black [59][60][61], carbon nanotubes [62][63][64][65], silver nanowire [20], Rochelle salt [30], gamma-ferrite additives [66], etc.…”

Nonlinear dynamics and stability analysis of a parametrically excited CNT-reinforced MRE viscoelastic cantilever beam

“…In this study an MRE+MWCNT-COOH (100 phr rubber, 10 phr epoxidized palm oil, 30 wt% of carbonyl iron particles (CIP), 0.1 wt% of MWCNT-COOH and additives) is used as a CNT-reinforced MRE and its elasticity modulus-magnetic field dependency is reported from [12] as:…”

“…In order to achieve an MRE which is able to behave like a viscoelastic material, CNT as an additional material could be added into the pure MRE. The mechanical properties of such materials have been studied by Aziz et al [12]. It is necessary to note that this configuration can be used as the main element of an active resonator without any additional layers.…”
