Enhanced photoresponse of graphene/conjugated polymer films

What is it about?

Composite films of chemically converted graphene (CCG) andwatersoluble 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.

Why is it important?

The preparation of the the photoresponsive films.
