Abstract

In this present work a novel material of Cellulose Nano Crystals (CNCs) grafted with butyl acrylate with ceric ammonium nitrate as initiator was prepared. The graft copolymerisation was done by changing the conditions like monomer (Butyl acrylate), amount of initiator concentration and temperature. The yield of grafted copolymer was observed in each case. Cellulose Nano Crystals was prepared by steam explosion method using banana fiber. The CNCs, grafted copolymer is then subjected to various analytical techniques such as FT-IR, XRD, SEM and TEM. From the FT-IR, the CH2 type of linkages was observed in the grafted copolymer showing increased transmittance of the polymers. From the X-ray diffraction method (XRD) the Crystalline and amorphous areas are calculated by Scherrer equation. The morphology of the prepared Cellulose Nano Crystals were evaluated using SEM and TEM.

Keywords: Cellulose Nano crystals, banana fiber, butyl acrylate, SEM, TEM.
