FT-IR and XPS analyses were carried out to examine the chemical structure and surface elements of CNC-Br and CNC-PDMAEMA.BIBB was anchored on the surface of CNC by esterification to prepare the ATRP initiator.As shown in Fig.1（b），unlike CNC，CNC-Br showed a strong FT-IR peak at 1740 cm-1.This peak corresponds to the stretching vibration of C=O from the ester group[19].A strong peak at 1280 cm-1 corresponding to C—O was observed in the FT-IR spectrum of CNC-Br（Fig.1 （b）） [20].The XPS spectrum of CNC-Br（Fig.2）showed a Br3d peak at 68 eV.It can be observed from Table 2 that the Br content in CNC-Br was 3.01%.These results suggest that BIBB was successfully grafted onto the CNC surface（reaction is shown in Scheme 1）.
