Recently, graphene oxide (GO) has been attracted for the last decade due to intrinsic excellent properties of graphene and oxygen functional groups on its surface, which enhance the dispersibility for scalability and processability. Especially, due to 2D-layered structure with high aspect ratio, GO is strongly considered as a promising barrier material in polymer nanocomposites, which are the most widely used for gas barrier applications. Despite all advantages of GO as inorganic filler, however, aggregation of GO in polymer matrix is a critical issue that reduces the effective gas barrier performance. Here, we prepared GO/poly(ethylene glycol) (GO/PEG) hydrogel nanocomposites by UV-induced in-situ polymerization that expecting that the oxygen functional groups of GO interact with hydrophilic parts of PEG. GO/PEG nanocomposites were successfully prepared, and improved gas barrier performance of GO/PEG nanocomposites was achieved with better dispersion in PEG matrix. |
