Abstract
MXene represents a highly promising class of two-dimensional materials characterized by its layered structure; however, the interlayer van der Waals forces result in aggregation of these NPs and limit their application . To address this challenge and enhancing their stability and applicability, strategies such as composite formation and surface modification are utilized. Notably, the transformation of MXenes into Janus structures has emerged as an effective strategy for improving functionality. Janus MXene nanosheets were synthesized via the Pickering emulsion method. In this method, one side of the MXene was masked with tapioca starch microspheres. Afterward, MXene was functionalized with dodecylamine (DDA), a hydrophobic agent. Subsequently, through thermal cycling (heat and sonication), the starch template was removed from the MXene surface. Then, Janus MXene nanosheets with an asymmetric structure are achieved. This study introduces a novel and cost-effective method for synthesizing hydrophilic/hydrophobic Janus MXene nanosheets. FTIR, Raman, XRD, and FESEM analyses collectively confirm the amphiphilic behavior and the two-dimensional structure of the synthesized Janus MXene nanosheets. This synthesis method is suitable and economical for Janus MXene production.
