Fabricating ordered porous monolayers from colloidal monolayer and multilayer

Both of the PSMA colloidal monolayer and multilayer were transformed to ordered porous monolayers in large-scale through selective solvent treatment. The pore formation is an in situ structure inversion process and the core-shell-like structure of PSMA colloid plays a critical role in pore formation and stabilization. The ordered porous polymer films, prepared by this method, can be used as a template for fabricating metal dot-arrays with large areas.
