Carbon is considered as an excellent electrode material due to its high electrical conductivity and mechanical strength . Pyrolytic carbon films are of interest for use in electroanalysis as they are often cheaper and more versatile as compared to glassy carbon or diamond-like carbon films . The molecular organisation of the precursors is known to affect the structure of the pyrolytic carbon and, therefore, highly organised cellulose is an attractive starting material as a possible source for pyrolytic carbon films on electrode substrates . Cellulose can be degraded to nanocrystalline cellulosic materials . Nanofibrils of cellulose or “whiskers” have been produced previously and they have been deposited on electrode materials using a layer-by-layer film deposition technique . These nanowhiskers are usually obtained by acid hydrolysis of native cellulose of cross-sectional dimensions are typically 4-20 nm and several hundred nanometers long, depending on the source of cellulose .
