The aim was to easily achieve clearer structural colors than ever before by layering nanoparticles using the Langmuir-Blodgett method. outermost surface of titanium dioxide (TiO2) particles with a particle diameter 15 nm modified long-chain fatty acids synthesize organo-modified TiO2. TiO2 spread on air/water interface, and obtained single-particle layer laminated different numbers layers obtain stepped multiparticle thicknesses 400-800 nm. exhibited clear color gradation. Compared previous studies involving use triiron tetroxide nanodiamonds 5 nm, without need for pretreatment. formed highly ordered structure demonstrating 11th-order reflection in out-of-plane X-ray diffraction. Additionally, compared other systems, modification rate high in-plane packing chains advanced. However, hue changed when samples were annealed at 50 °C h. A method subsequently proposed introduce hydrogen-bonding functional groups into suppress this behavior. pursuit ease stability expression will lead future applications cosmetic science.
