| dc.description.abstract | Graphene oxide (GO) can be used as an electron acceptor for polymers. The generation of the exciton in such materials is intimately related to the optical band gap. Polyacrylamide (PAAm) - graphene oxide (GO) composites were prepared via free radical crosslinking copolymerization with GO content varying in the range between 5 and 40 mu l of GO. The influence of the GO content on the optical properties of the composites is characterized by ultraviolet visible spectrophotometer. The optical band gap of the composite has been calculated by using Tauc's model. The tail width of the localized states has been calculated by using Urbach's relation and the values of Urbach's energy with the variation of GO have been found from 289 to 296 eV. The results demonstrated that GO can be well dispersed in the PAAm-GO composites and consequently the optical band gap has been correlated with the various amounts of GO. (C) 2017 Elsevier Ltd.
