This study investigates the possibilities offered by the development of graphene environment technology that can contribute to new and effective approaches for the transition to an ecologically benign ecosystem. To analyze the research and development progress in graphene environment technology, graphene environment technology research trends of South Korea for the years 2009–2020 are investigated by acquiring information pertaining to national research and development projects related to graphene environment technology from the National Science and Technology Information Service. Both structured and unstructured data are analyzed using diverse text-mining methods, such as keyword frequency analysis, association rule mining, and topic modelling. The results indicate that graphene research in South Korea is focused primarily on graphene use in batteries and energy-storage devices, such as solar cells, fuel cells, and secondary batteries. This study can help understand the manner by which the South Korean government has been investing in the research and development of graphene environment technology; additionally, it discusses the future applications and prospects of graphene for the next decade. |
