Enhanced photoresponse of large-sized photoactive graphene composite films based on water-soluble conjugated polymers

Chem Commun (Camb). 2013 Jun 21;49(49):5538-40. doi: 10.1039/c3cc40563j.

Abstract

Composite films of chemically converted graphene (CCG) and water-soluble polythiophenes (P3TOPS and P3TOPA) were prepared by a LBL method using a suspension of negatively charged CCG-P3TOPS sheets and a solution of positively charged P3TOPA. The composite films show enhanced photoresponse due to photoinduced electron transfer from the polythiophenes to CCG.
