通过简单的无表面活性剂的声化学反应合成了Fe 3 O 4纳米粒子。不使用惰性气氛的室温合成是本工作的新奇。研究了不同工艺参数对产物形貌的影响。样品的磁性能也进行了研究，使用交变梯度磁力仪。Fe 3 O 4纳米粒子表现出铁磁行为，在室温下的饱和磁化强度为66 emu/g，矫顽力为39 Oe。为了制备磁性纳米复合材料，将Fe 3 O 4纳米颗粒添加到聚乙烯醇（PVA）中。纳米粒子的加入可以提高PVA基体的热稳定性和阻燃性能。(C)2014年韩国工业与工程化学学会。Elsevier B. V.出版，保留所有权利。
Fe3O4 nanoparticles were synthesized via a simple surfactant-free sonochemical reaction. Room temperature synthesis without using inert atmosphere is the novelty of this work. The effect of different parameters on the morphology of the products was investigated. The magnetic properties of the samples were also investigated using an alternating gradient force magnetometer. Fe3O4 nanoparticles exhibit a ferromagnetic behavior with a saturation magnetization of 66 emu/g and a coercivity of 39 Oe at room temperature. For preparation magnetic nanocomposite, Fe3O4 nanoparticles were added to the polyvinyl alcohol (PVA). Nanoparticles can enhance the thermal stability and flame retardant property of the PVA matrix.
