Extraction of cellulose and preparation of nanocellulose from sisal fibers

et al. 2007

In this work a study on the feasibility of extracting cellulose from sisal fiber, by means of two different procedures was carried out. These processes included usual chemical procedures such as acid hydrolysis, chlorination, alkaline extraction, and bleaching. The final products were characterized by means of Thermogravimetric Analysis (TGA), Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Differential Scanning Calorimetry (DSC) and Scanning Electronic Microscopy (SEM). The extraction procedures that were used led to purified cellulose. Advantages and disadvantages of both procedures were also analyzed. Finally, nanocellulose was produced by the acid hydrolysis of obtained cellulose and characterized by Atomic Force Microscopy (AFM).

“…Chemical analysis of the untreated and alkali treated fibers was carried out as per the standard procedure (Chattopadhyay and Sarkar 1946;Sarkar et al 1948;moran et al 2008). In this analysis, the percents of α-cellulose, hemicellulose and lignin were determined.…”

The coconut palm tree leaf sheath fibers were analyzed by FTIR spectral analysis, Chemical, X-ray and thermo gravimetric methods to assess their suitability as reinforcements in the preparation of green composites. The morphology of the untreated and alkali treated fibers was studied by scanning electron microscopic method. The FTIR and chemical analyses indicated lowering of hemi-cellulose content by alkali treatment of the fibers. The X-ray diffraction revealed an increase in crystallinity of the fibers on alkali treatment. The thermal stability of the fibers was found to increase slightly by alkali treatment. The tensile properties of these fibers increased on alkali treatment. The mechanical and other physical properties indicated that these fibers were suitable as reinforcements for making the green composites.

The structural features and fracture morphology of raw and chemically treated pineapple leaf fiber have been studied using scanning electron microscopy. Pineapple leaf has a multicellular structure, and alkali treatment clearly reveals the ultimate fibers. Surface morphology progressively changes with gradual removal of noncehulosic constituents like lignin and hemicellulose. Fracture morphology shows that there is a uniform sharing of the load in the ultimate fibers of raw pineapple leaf, whereas treated leaf shows irregular fractures characterized by the slippage of individual ultimate fibers.
