Abstract

Abstract: In this work, we developed a strategy to fabricate self‐assembled aggregates encapsulating graphene from direct exfoliation of graphite. Naphthalene‐anhydride‐appended glutamic acid (NG) and pyrene‐appended glutamic acid (PG) were utilized to exfoliate graphite to generate few‐layer graphene in basic aqueous media. Acidification‐triggered self‐assembly of PG could encapsulate graphene sheets to give graphene@microsheet hybrids. Melamine (Mm) was introduced to induce the morphological transformation of PG from microsheets to twisted fibers with columnar packing. In the presence of graphene, this transformation allowed the fabrication of twisted‐fiber‐encapsulated graphene (graphene@twist fiber). Tricomponent hybrids were also built up via in situ preparation of gold nanoparticles (AuNPs) on the negatively charged surface of few‐layer graphene during the self‐assembly process. This study presents an approach to construct directly exfoliated graphene‐based hybrids through self‐assembly. [ABSTRACT FROM AUTHOR]
