| 제목 | Composites based on silane-functionalized graphene oxide |
| 초록 | Abstract We provide a new method for composites and Organic Photovoltaic cells(OPVs) by using silane-functionalized graphene oxides(sGOs). The functionalization of the oxygen-containing groups on the surface of GO was converted by the self-assembled monolayers(SAMs) to amine, epoxy, and alkyl groups. The formation of Si-O-C, Si-O-Si, and Si-H bonds indicated that the reaction between silane molecules of SAMs and functional groups of GO occurred successfully. The bonding strength of a carbon fiber/epoxy composite was increased by 54% after the addition of a sGO contained amine groups. Another case of OPVs based sGO(GPTMS, MTES), the power conversion efficiency(PCE) value increase to 3.00 and 3.08%, respectively. It is considered that the increase in the PCE value is caused by the bandgap alignment.
