In this work, a multifunctional separator (TB-BAA/SWCNT/PP) is developed through spin coating of a novel zwitterionic microporous polymer (TB-BAA) on the gutter layer constructed from single-walled carbon nanotubes (SWCNT), where commercially available polypropylene (PP) separator is used to act as the mechanical support. SWCNT in this study serves as the first modification layer to decrease the size of the macropores in the PP separator, while the ultrathin TB-BAA top barrier layer with the presence of zwitterionic side chains allows the creation of confined ionic channels with both lithiophilic and sulfophilic groups. Due to the presence of available chemical interactions with lithium polysulfides, selective ion transport can be foreseen through such separator. In this regard, shuttle effect that is frequently encountered in Li-S battery can be suppressed effectively via implementing the as-obtained functional separator, resulting in the creation of credible and stable sulfur electrochemistry. The TB-BAA/SWCNT/PP-based Li-S battery has been investigated to possess high cycling ability (capacity fading per cycle of 0.055 over 500 cycles at 1 C) together with decent rate capability (736.6 mAh g�1 at 3 C). In addition, a high areal capacity retention of 5.03 mAh cm�2 after 50 cycles can be also obtained under raised sulfur loading (5.4 mg cm�2). © 2022 Elsevier Inc. date: 2022 publisher: Academic Press Inc. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85135853409&doi=10.1016%2fj.jcis.2022.08.025&partnerID=40&md5=61a22458c5eb81205c5992f28b7a42e9 id_number: 10.1016/j.jcis.2022.08.025 full_text_status: none publication: Journal of Colloid and Interface Science volume: 628 pagerange: 1012-1022 refereed: TRUE issn: 00219797 citation: Sun, S. and Han, L. and Hou, J. and Yang, Y. and Yue, J. and Gu, G. and Chuah, C.Y. and Li, J. and Zhang, Z.
