Abstract: Recently, a lot of methods were devised to prepare an ordered arrangement of nanomaterials, such as self-organization, electrophoretic deposition, and Langmuir-Blodgett(LB), etc. The LB technique was proven a powerful and simple method to prepare the high-density nanoparticle monolayer and multiplayer film with controllable layer numbers and thickness. In this article, we introduced an improved LB method to fabricate the FePt nanoparticle monolayer film. The LB monolayer of FePt nanoparticles was fabricated on different substrates using a cycling compression method. The monolayers have a smooth surface and a high-density structure on hydrophobic surface as shown by the TEM and AFM image. The results show that the uniformity and stability of the monolayer can largely improve by this method, and the surface morphology of monolayers was varied between the substrates.
