We demonstrated a large-area nanopatterning technique with the help of a non-close-packed PS sphere layer over a large-area substrate. The non-close-packed PS sphere layer is fabricated by blade coating method. It was demonstrated that non-close-packed PS spheres can be achieved within an area of 18 cm × 25 cm on a rigid glass substrate and within an area of 10 cm × 10 cm on a flexible substrate. We also demonstrated that the blade-coated non-close-packed PS sphere layer was suitable for the mass production of vertical organic transistors over a large area.
