Application example of polystyrene nanoparticles: "Three-dimensional ordered porous structure"
Using polystyrene nanoparticles with uniform particle size as a mold allows for the creation of regular porous materials with nanosized pore diameters from various materials.
Using arranged polystyrene nanoparticles as a mold, after filling the spaces between the particles with another material and solidifying it, removing the microparticles through methods such as firing or dissolution results in a three-dimensional void structure that is inverted from the original colloidal crystal. This is referred to as "3 Dimensionally Ordered Macroporous" (3DOM) or "inverse opal structure." **Features** - Possesses a highly ordered porous structure in three dimensions - The size of the microparticles used as a mold allows for free control over the size of the voids - Various materials can be used for the void structure - High surface area per unit volume - Low transport resistance of substances due to high porosity For more details, please contact us or download the catalog.

Company information
The advent of nanoscale materials has made it possible for materials science to have direct connections with biology, optics, and other fields. Photonic crystals and structural colors found in birds and insects are good examples of this. Until now, we have worked with various materials such as semiconductors, carbon materials, metals, oxides, and polymers. Leveraging this experience, we hope to be able to assist you in solving your "problems."
