1H,1H,2H,2H-perfluorodecyl acrylate (PFDA) was grafted using electron beam irradiation to hydrophobize the cellulose nanocrystals' (CNC) surface. FT-IR and XPS measurements showed that PFDA was grafted onto the CNC surface. The results of SEM and EDS showed that PFDA was grafted to the CNC surface in a spherical shape. As a result of the XRD measurement, it was confirmed that the crystallinity of PFDA decreased as it was grafted onto the CNC surface. As a result of the contact angle measurement, it was shown that as the PFDA was grafted on the CNC surface, the contact angle increased, which means that the hydrophobicity increased.
