“…4) glycosidic linkages of the b-D-glucopyranosyl units of cellulose (Marcovich et al, 1996). Regarding the band at 1690-1590 cm À1 , it corresponds to the amide I vibrations (common to proteins, Pereda et al, 2008) and also to adsorbed water molecules in noncrystalline cellulose (Jayaramudu et al, 2009). Moreover, the existence of this band in the spectrum of neat cellulose confirms that it is highly but not 100% crystalline.…”

“…This is quite expected as hemicellulose is soluble in aqueous NaOH (alkali) solution. [6,23] The band C=C in the tassel fiber represents the aromatic vibration at 1500 cm À1 from methoxyl groups of lignin. [13] This band was significantly reduced in the alkali-treated sample because of the removal of most of the hemicellulose and lignin from the tassel fiber through treatment.…”

“…[4] This report focuses on the growth of specialized techniques for the manufacture of natural fillers as reinforcing agents designed for biocomposite applications. Chemical composition, structure, and physical and thermal properties [5][6][7] of fibers/fabrics can be used to estimate and approximate their capabilities, [8][9][10][11] hence maize tassel can be used as protective material (filler) in biocomposite applications.…”

This article reports on the extraction and characterization of novel natural cellulose fibers obtained from the maize (tassel) plant. Cellulose was extracted from the agricultural residue (waste biomaterial) of maize tassel. The maize tassel fibers were obtained after treatment with NaOH and were carefully characterized while the chemical composition was determined. The chemical composition of the maize tassel fibers showed that the cellulose content increased from 41% to 56%, following alkali treatment. FT-IR spectroscopic analysis of maize tassel fibers confirmed that this chemical treatment also shows the way to partial elimination of hemicelluloses and lignin from the structure of the maize tassel fibers. X-ray diffraction results indicated that this process resulted in enhanced crystallinity of the maize tassel fibers. The thermal properties of the maize tassel fibers were studied by the TGA technique and were found to have improved significantly. The degradation temperature of the alkali-treated maize tassel fiber is higher than that of the untreated maize tassel fibers. This value convincingly showed the potential of maize tassel fibers for use in reinforced biocomposites and waste water treatment.

“…However, as the spectrum of these fibers is narrow, the identification of new natural fibers/fabrics has turned into an active research challenge in the bio-composites materials community. For example, in the last years fibers/fabrics such as: Arundo donax L. [26]; Cissus quadrangularis [27]; Abelmoschus esculentus [28]; Ferula communis [29]; Cynara cardunculus L. [30]; Althaea officinalis L. [31]; Sansevieria ehrenbergii [32]; Prosopis juliflora [33]; and Polyalthia cerasoides [34], have been suggested as interesting alternatives to reinforce novel composites.…”
