✦ Synopsis

Abstract

An ultra‐fast fabrication of large‐scale colloidal PCs via spray coating was demonstrated. The latex spheres with hydrophobic core and hydrophilic shell were designed, and the latex shell with abundant COOH groups resulted in strong hydrogen bonding interaction among latex spheres, which boosted latex arrangement during the spray procedure. The resultant samples with area of 7 × 12 cm^2^ were easily fabricated within 1 min on different substrates. This ultra‐fast fabrication procedure would be of great importance for the practical application of PCs for optic devices and functional coatings.
