Cellulosic nanomaterials - including cellulose nanocrystals (CNC),cellulose nanofibres (CFS) [1,2] along with their composites are promising materials for many novel applications [3-5] owing to their unique properties that include excellent mechanical strength [6],self-assembly,liquid crystalline behavior [7.8] and optical properties ranging from transparent to translucent [9]. Controlled acid hydrolysis of native cellulose soures using sulfuric acid is commonly used to synthesise rod-shaped cellulose nanocrystals [10],which are electrostatically stabilized [11] by the sulfate ester moieties [12] on their surfaces. The acid hydrolysis typically results in the formation of cellulose nanocrystals of width 5-10 nm and length 100-300 nm[13].
