Magnetorheological (MR) fluids have been successfully utilized in versatile fields but are still limited by their relatively inferior long-term dispersion stability. Herein, bio-inspired passion fruit-like Fe3O4@C nanospheres were fabricated via a simple hydrothermal and calcination approach to tackle the settling challenge. The unique structures provide sufficient active interfaces for the penetration of carrier mediums, leading to preferable wettability between particles and medium oils. Compared with the bare Fe3O4 nanoparticle suspension, the resulting Fe3O4@C nanosphere-based MR fluid exhibits desirable stability and relatively low field-off viscosity even at a high particle concentration up to 35 vol %.

生物启发的激情果状Fe3O4 @ C纳米球,具有高稳定性的磁流变性能。

磁流变(MR)流体已成功地应用于各种领域,但仍受到其长期较差的分散稳定性的限制。在本文中,通过简单的水热和煅烧方法制备了受生物启发的百香果状Fe 3 O 4 @C纳米球,以解决沉降难题。独特的结构为载体介质的渗透提供了足够的活性界面,从而导致了颗粒与介质油之间的最佳润湿性。与裸露的Fe 3 O 4纳米颗粒悬浮液相比,生成的Fe 3 O 4即使在高达35体积%的高颗粒浓度下,基于C纳米球的MR流体也表现出期望的稳定性和相对较低的场截止粘度。
