The partnership of three laboratories of our department led to an inside back cover article publication of the Nanoscale magazine (IF 7.23).
The laboratory of Polymers led by professor Constantinos Tsitsilianis with the collaboration of the laboratory of Statistical Thermodynamics and Macromolecules (prof. Vlasis Mavrantzas) and the laboratory of Nanotechnology and Advanced Μaterials (prof. Constantine Galiotis) published an article with title:
3-Arm star pyrene-functional PMMAs for efficient exfoliation of graphite in chloroform: fabrication of graphene-reinforced fibrous veils
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.
