The major issues in the fabrication of periodic nanostructure arrays are the high costs, low patterning speed, and small patterning area. Spray coating of polystyrene colloids (PS) and ion-etched nanochannels on a flexible, chemical resistance polymer (PDMS) thin foil, enable reusable soft masks for deposition and imprinting techniques. Spray coating leads to a self-assembled colloidal film, where every nanosphere can be used as lenses for lithographic fabrication methods. We prove the application principle and the morphology by scattering methods, contact angle analysis and spectroscopic imaging methods. This study offers a novel routine for cost effective nanofabrication which is wide applicable in nanoscale materials.
