摘要

A method is developed to prepare asymmetric mesoporous carbon microparticles by neutral interface-guided 3D-confined self-assembly of block copolymer/homopolymer blends, followed by a self-templated selective direct carbonization strategy.

Abstract

Shape control of mesoporous carbon microparticles (MCMPs) is of critical importance; in particular, asymmetric shapes that can yield unique properties have attracted significant attention. However, the tailored synthesis of asymmetric MCMPs with ordered structures remains challenging. Herein, we report a facile route to prepare asymmetric MCMPs by dynamic neutral interface-guided 3D-confined self-assembly (3D-CSA) of block copolymer/homopolymer (BCP/,h,P) blends, followed by a self-templated selective direct carbonization strategy. BCP/,h,P Janus microparticles with ordered hierarchical mesostructures were prepared with emulsion solvent evaporation-induced 3D-CSA. The continuous phase of BCP domains was then crosslinked. Composite asymmetric MCMPs are successfully generated after selective carbonization of the crosslinked continuous phase. This method allows tuning the shape of MCMPs easily by varying the blending ratio of BCP/,h,P. The composite asymmetric MCMPs combine the advantages of asymmetric shape, ordered structure, high specific surface area, chemical inertness and thermal stability and could provide great possibilities for applications in catalysis, drug delivery, energy conversion and storage.
