Abstract

original image

Hanging on: Pristine graphene was grafted with conjugated polymers through addition and propagation of diradicals generated from Bergman cyclization of enediyne-containing dendrimers. The surface functionalization was confirmed with TGA, FTIR and Raman spectroscopy, and AFM analysis. The sp2 network of graphene is only slightly destroyed, as revealed by conductivity measurements.
