Short revision of the article:
Tailor-made, well-defined, 3-arm, star-shaped pyrene-functional PMMAs were designed as dispersing agents for the liquid phase exfoliation of graphite. Stable few-layered graphene sheets were achieved in chloroform, with very low polymer/graphite mass ratio. Additionally, detailed all-atom Molecular Dynamic simulations were performed to provide insights into the exfoliation mechanism. Finally, the G@(PMMA-Py)3 hybrids were successfully incorporated into a PMMA matrix by electrospinning to fabricate graphene-based nanocomposite fibrous veils. The PMMA/G@(PMMA-Pyn)3 elecrospun fiber mats exhibit a modulus enhanced by a factor of 4.4 for the 1.5 wt.% G@(PMMA-Pyn)3 nanocomposite.
