In this this study, bleached kraft pulp fibers was obtained from Eucalyptus camaldulensis wood chips. Then, those bleached kraft pulp fibers were modified with 2,2,6,6-tetramethyl 1-1-piperidinyloxy (TEMPO), N-hydroxyphthalimide (PINO) and periodat (IO4−). Afterward, the obtained samples were passed through high pressure homogenizator to convert them to modified nanocellulose. Chemical and morpohlogical analysis of the obtained products were investigated by using HPLC (High Performance Liquid Chromotography), FTIR (Fourier Transform Infrared Spectroscopy) and SEM (Scanning Electron Microscopy) device. After modifications, it was determined that molecular and amorph structure altered the chemical structure of the samples. Periodate was more effective on glucose over to tetramethyl 1-1-piperidinyloxy and N-hydroxyphthalimide. In the morphological analysis, 2,2,6,6-tetramethyl 1-1-piperidinyloxy caused more effective in that aspect of fibril structure. Studies regarding nano scale have been increased in the last years,. In the present study, nanocellulose productions and their modification were succesfully carried out. When investigated chemical and morphological properties of the obtained modified nanocellulose, it was determined that used chemicals led to different effects on the nanocellulose. In the light of the obtained data, it has been thought that the present study will make extra contribution to the literature.
