제목 | Preparation and characterization of carbon dots/dialdehyde cellulose nanofibrils composite |
초록 | Dialdehyde cellulose nanofibrils (DACNF) were prepared by periodate oxidation of cellulose nanofibrils (CNF) and carbon dots (CDs) with amine functionalities were obtained by hydrothermal method. CDs/DACNF composites were prepared by crosslinking DACNF with CDs via Schiff’s base formation. Dialdehyde modification decreased the crystallinity and fiber length of CNF. Chemical composition and presence of amine functionalities on CDs were confirmed by XPS and FTIR. Crosslinking of DACNF by CDs was characterized by FTIR and XPS analysis. This research was supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education (No. 2018R1A6A1A03025582) |
