“…The improvement of the elastic moduli is slightly superior to that obtained with particulate fillers [3][4][5][6][7][8][9]. The natural strands as jute, kenaf, flax, are the most effective cellulosic reinforcement fibers [2,[10][11][12][13][14][15].…”

“…According to this, higher amounts of maleated polypropylene were added with respect to PP as much reinforcement was incorporated. The effect of the amount of MAH-PP with respect to the PP matrix was already studied in our laboratory [14]. Thus, the amount of MAH-PP should not increase too much to avoid a diminishing of the mechanical properties due to the effect of the low molecular weight of the PP chains of MAH-PP.…”

“…Thus, the amount of MAH-PP should not increase too much to avoid a diminishing of the mechanical properties due to the effect of the low molecular weight of the PP chains of MAH-PP. The addition of 8 wt.% of MAH-PP would produce a decrease on the mechanical properties of the final composite [14].…”

“…In particular, the peak presented at~1725 cm −1 in all the enzyme hydrolysed HHB samples is attributed to ν(C=O) stretching modes of carbonyl and ester groups, as well as the presence of aldehydes and ketones from pectin and xylan (hemicellulose) traces [34]. As a result of sodium hydroxide pretreatment and subsequent enzyme hydrolysis, this peak appeared to be shifted to a lower wave number at 1710 cm −1 suggesting an altered interaction of the carbonyl groups in the polymer matrices, which was likely to be in forms of C=O-O-C=O bonding structure in the original (untreated) material [35]. The bands centred at 1590 and 1507 cm −1 , on the other hand, can be assigned for ν(C=C) in-plane stretching vibrational modes of aromatic rings associated to the lignin content [33].…”

The physicochemical properties of hemp biomass structure to pretreatment and enzymatic hydrolysis were investigated to improve upon reducing sugar production for biofuel development. Sodium hydroxide pretreated biomass (SHPB) yielded maximum conversion of holocellulose into reducing sugar (72 %). Scanning electron microscopy (SEM) revealed that enzymatic hydrolysis generated regular micropores in the fragmented biomass structure. The thermogravimetric analysis (TGA) curve suggested the degradation of hemicellulose and cellulose, which conformed well to the subsequent nuclear magnetic resonance (NMR) studies indicating the presence of α-and β-glucose (28.4 %) and α-and β-xylose (10.7 %), the major carbohydrate components commonly found in hydrolysis products of hemicellulose and cellulose. Attenuated total reflection Fourier transform infrared (ATR-FTIR) spectra showed stretching modes of the lignin acetyl group, suggesting the loosening of the polymer matrix and thus the exposure of the cellulose polymorphs. X-ray diffraction pattern indicated that enzymatic hydrolysis caused a higher crystallinity index (36.71), due to the fragmentation of amorphous cellulose leading to the reducing sugar production suitable for biofuel development.
