Bio-nanomaterials have been a revelation in the field of nanotechnology giving a pollution free option for most of the applications. Imitation of the nature paves way for most of the modern inventions. So too the biopolymers and bionanomaterials which are showing encouraging signs for the future of material science. Cellulose being a vastly available biopolymer and having the provision of modification, it provides room for usage in many fields.
Cellulose was extracted from coconut husk by soda pulp method and modified to cellulose acetate by acetylation. Cellulose nano-crystals were synthesized by acid-hydrolysis method. Structural elucidation is done by FT-IR analysis and their thermal properties were studied by TGA/DTA analysis. TEM images confirm the nano-crystals to be in nano-scale.
