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/

P) blends

followed by a self-templated selective direct carbonization strategy. BCP/

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/

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.
