The Soft Matter Science and Engineering Center of the University of Chemical Technology announced that its researchers have worked with the Lawrence Berkeley National Laboratory team to discover a new type of magnetic fluid that can control magnetic nanoparticles at the water-oil interface. The self-assembly of Neodymium Disc Magnet supplier (https://www.zhijiangmagnet.com/product/neodymium-magnet/) finally led to the successful transformation of ferromagnetic fluid from paramagnetism to ferromagnetism.
Generally, the magnet is no longer a hard solid, but can also be a flowing liquid. According to reports, solid magnetic materials are ubiquitous in small household appliances such as refrigerators, and large space equipment such as magnetic navigation devices. Generally, liquid magnetic materials such as conventional ferrofluids have a flexible shape, but do not have magnetic poles themselves, and can only be magnetized by an external magnetic field to exhibit specific magnetism.
The ferromagnetic droplets or liquid magnets found in this study have both the magnetic properties of solid magnets and the fluidity of liquids. The combination of the two forms a new magnetic soft material. The researchers combined water-based magnetic fluid materials with organic Phase, the carboxylated ferric oxide magnetic nanoparticles dispersed in the water phase and the aminated cage silsesquiane are dissolved and mixed in the adjacent oil phase.
SmCo Ring Magnets Company ( https://www.zhijiangmagnet.com/product/smco-magnet/ ) Oxane interacts at the water-oil interface, self-assembles in situ to form a magnetic nanoparticle surfactant, which adsorbs to the interface and blocks the phase change to form ferromagnetic droplets. The measurement of the hysteresis loop of the droplet at room temperature shows that, unlike the conventional paramagnetic magnetic fluid, the droplet exhibits a certain degree of remanence and coercivity, and is transformed into ferromagnetism.
