Fabrication and characterization of block copolymer micelle multilayer films prepared using dip-, spin- and spray-assisted layer-by-layer assembly deposition

► All block copolymer micelle (BCM) multilayer films were prepared using dip-, spin- and spray-assisted layer-by-layer (LbL) methods. ► The resultant films showed specific film growth mechanisms such as linear and exponential growth. ► The porosity was readily controlled from 2.6% to 55.9% by manipulating the LbL deposition methods and thickness. ► The distinct surface morphologies were demonstrated via the respective assembly methods, despite identical preparation conditions.
