Synthesis of a large-scale highly ordered porous carbon film by self-assembly of block copolymers

Abstract

Made to order: The synthesis of well-defined porous carbon films involves four steps: 1) monomer-block copolymer film casting, 2) structure refining through solvent annealing, 3) polymerization of the carbon precursor, and 4) carbonization. The resulting films, such as that depicted, have potential as separation membranes, chemical sensors, and catalysts.
