A magnetic emulsifier is synthesized by using the two-step method. Firstly, Fe3O4 nanoparticles are synthesized and then modified with silane coupling agent 3-(methacryloyloxy) propyltrimethoxysilane (KH-570). Secondly, the final composite particles are synthesized by the reaction between emulsifier octylphenol polyoxyethylene ethe OP-10 (C8H17C6H4O(CH2CH2O)10H) and modified Fe3O4 nanoparticles by silane coupling agent KH-570. After then the products are characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), Raman spectroscopy, thermogravimetric analysis (TGA), and X-ray diraction (XRD). The result shows that the mean diameter of Fe3O4 nanoparticles is about 22.7 nm and the silane coupling agent KH-570 can be effectively modified Fe3O4 nanoparticles. In addition, this paper investigated the best hydrolysis conditions of coupling agent and the optimum reaction conditions of silane coupling agent on the Fe3O4 nanoparticles.
