Aggregation Effect in Polymer Graphene Composites for Optical Sensing Applications

Abstract

We measured the aggregation behavior of polyfluorine (PFO) films blended with graphene oxide (GO) and reduced graphene oxide (RGO) using optical spectroscopy spectroscopy. We observed the changes relative intensity of 0-0 to 0-1 in the emission spectra in polymer graphene composite films. The composite films have more H like aggregation compared to pristine film. In addition, strong photoluminescence quenching observed in PFO-RGO compared to PFO-GO. Our study shows that polymer graphene composites can be used as optical sensing materials.
