Lignin is one of the most abundant, but under-utilized natural polymers in the biosphere. Recently, lignin nanofibers exhibiting lignin’s inherent functionalities were developed, so lignin was suggested as a new fiber material. When considering the properties of final products, however, lignin nanofibers made with water-soluble polymers require an insolubilization process. In this study, electrospun lignin nanofibers were prepared and modified with plasma treatment for the purpose of hydraulic stabilization. Morphology of plasma-treated lignin nanofiber webs before and after immersion in water was observed by FE-SEM. Conformational changes were examined by FT-IR and XRD. XPS was used to investigate the surface of lignin nanofiber webs after plasma treatment. Mechanical and antimicrobial properties of plasma-treated lignin nanofibers were examined, and compared to those of lignin nanofibers treated with existing mechanical insolubilization method. |
