Abstract

Microporous organic polymers have special structures and important properties, but their hard processability severely limits their practical applications. In this study, we synthesize nitrogen-containing microporous organic polymer nanofilms by using an interfacial polymerization strategy and then use them as a template to fabricate novel nitrogen-doped microporous carbon nanofilm/molybdenum disulfide (NMC-nanofilm@MoS2) composites. Owing to the surfaces of NMC nanofilms homogenously covered by MoS2 nanosheets to form an alternating layer-by-layer nanostructure of MoS2 and NMC nanofilms, the obtained composite-based electrodes exhibit superior electrochemical performances to the previously reported MoS2-based composites, with a specific capacity of as high as 1190 mA h g−1 after the 500th cycle at a current density of 1.0 A g−1, and 908 mA h g−1 after the 2000th cycle at a current density of 2.0 A g−1.
