Fabrication of colloidal crystals on hydrophilic/hydrophobic surface by spin-coating

► PS colloidal crystals were fabricated on the hydrophilic and the hydrophobic surfaces by spin-coating. ► The structure of the spin-coated PS colloidal crystals depended on the surface wettability. ► The mechanism for the growing multilayers of self-assembled spheres by the spin-coating method is discussed. ► This work demonstrates the rapid and simple method for the fabrication of colloidal crystal of TiO2 hollow spheres.
