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.

In this study, we unprecedentedly fabricated a Langmuir monolayer of polytetrafluoroethylene (PTFE) using novel method. The prevailing opinion is that it impossible for completely insoluble substance, such as PTFE, to form monolayers on the water surface/Langmuir monolayers, owing limitations in preparation A solid tablet was prepared PTFE and floated surface day night detect pressure. When two-dimensional compression applied, pressure-area isotherm obtained, suggesting formation monolayer. Upon transfer substrate, an X-ray photoelectron spectrum derived from fluorine atoms atomic force microscope image thickness single fluorocarbon chain obtained. contact angle substrate measured, value equivalent three-dimensional state Thus, study first produce Langmuir-Blodgett film surface. Because C-F bonds chains are inherently polarized, predicted molecules would be more stable when liberating interacting with than through intermolecular interactions tablet.
