The interfacial bond strength and field-induced storage modulus of magnetorheological elastomers can be enhanced by using flower-like active particles.
In this study, monodisperse Fe3O4 nanoparticles were synthesized successfully using a sonochemical method in the presence of 3-aminopropyltriethoxysilane (APTES). The morphology, microstructure and magnetic properties bare APTES-coated investigated detail by TEM, XRD, FTIR SQUID. It was found that showed relatively good dispersion with narrow size distribution 8.4 ± 2.1 nm diameter. functionalization proved to be covalent linking between APTES. field-dependent magnetization curve indicated...
Recent studies indicated the electrorhological (ER) effect of ER fluids with flower-like particles were more significant than those traditional sphere particles, but whether special morphology can enhance properties magnetorheological (MR) remains unclear. To address issue, cobalt (FCP) and (SCP) synthesized, two kinds MR compared. Particle characterization results indicate have difference in morphology, little crystal structure, particle size, magnetic properties. The FCP based (FCP-MRFs)...
In this study, zinc ferrite (ZnFe 2 O 4 ) nanocrystal clusters were synthesized successfully with a surfactant-assistant solvothermal method and investigated as potential magnetorheological material. The morphology, structure, magnetic properties of the obtained ZnFe in detail using scanning electron microscope, transmission X-ray diffraction, superconducting quantum interference device. It was found that showed well-defined shape homogeneous dispersion narrow size distribution 276 nm...
The interface between the particles and carrier fluids has an important influence on performance of magnetorheological fluid (MRF). In this study, ionic liquids silicone oils with same viscosity different surface tensions were used as to prepare two carbonyl iron powder (CIP) fluids. rheological properties evaluated by MCR301 rotating rheometer. experimental results indicate that liquid-based MRF showed higher shear yield strength more significant MR effect than oil-based ones in magnetic...
Co nanofibers were synthesized and used to prepare magnetorheological fluids with excellent MR effect sedimentation stability.
Magnetorheological (MR) fluids are smart materials that show enormous potential in vibration control, mechanical engineering, etc. However, the effects of solid-liquid interface strength and interaction between carrier liquid molecules on properties sedimentation stability MR have always been unresolved issues. This work presents a new type fluid has novel liquid, i.e., silicone oil (SO) mixed with hydroxyl-functionalized ionic (IL-OH). An all-atomic Fe/SO/IL-OH model for studying...
It is a challenge to make artificial muscles with tunable stiffness capacities. The key develop composite as well self-healing properties and stretchability. In this work, we design amorphous TiO2 particles poly(dimethylsiloxane) (PDMS) matrix cross-linked metal–ligand interactions. PDMS enables the have excellent stretchability, while interactions between can be enhanced by applying an electric field, which provides field-controlled stiffness. storage modulus increased 180% at 4 kV/mm. of...
