“…Wang et al [45] also stated that increasing the cotton linter nanocellulose content within soy protein thermoplastic resulted in a decreased optical transmittance (Tr) of nanocomposite films, as congruently described by Pelissari et al [32] that banana nanocellulose reinforced with banana starch behaved in the same way. The findings of this study are concurrent with the studies of Besbes et al, [46] Bilbao-Sainz et al, [47] and Thiripura Sundari et al, [48] in which, the nanocomposite functional properties could be enhanced when the nanofibers are well distributed in the polymeric matrix. The lower opacity value of the films might be due to the roughness of the nanocomposites surface area.…”

Sugar palm fiber (SPF) is an agro‐waste plant that can be used as potential source of biomass for various biomaterial applications. In this study, sugar palm nanofibrillated cellulose (SPNFC) that was isolated from SPF was used as a nanofiller to reinforce sugar palm starch (SPS) to produce bionanocomposites. To attain SPNFCs, SPF was undergo strong acid and alkaline treatments. Later, the SPNFCs were prepared from SPFs via high pressurized homogenization process. The reinforcement of SPNFCs (0‐1.0 wt%) and SPS is done by using solution casting methods. The films were characterized in terms of physical properties such as light transmittance, moisture content, water solubility, and water absorption. The resulting nanocomposites permitted better water resistance, low moisture absorption, and low light transmittance as compared to control SPS film. Adding 1 wt% SPNFCs loading significantly improved the water absorption and water solubility of the composite film by 24.13% and 18.60%, respectively, compared with the control SPS film. This was attributed to the high compatibility between the SPNFCs and SPS matrixes, which composed of the multi‐hydroxyl polymer having three hydroxyl groups per monomer. Thus, this study is to show the potential of SPS/SPNFCs nanocomposite films in packaging industries.

“…A small peak was observed at 1700 in the raw sample only and it was also observed by Krishnan and Ramesh, (2013) [20], Tibolla et al,(2014b) [21] as well as Sundari and Ramesh, (2012) [22] and they attributed to vibration of uronic acid ester linkages of carboxylic groups and the acetyl groups of p-coumeric acid as well as ferulic acid of hemicelluloses and / or lignin. The sharp peak at 1629 in micro-particles was probably due to adsorbed water and a similar trend was observed by George, and Narayanankutty, (2016) [23].…”

“…3c, d). These changes occurred from 2000 to 1500 cm -1 and from 1500 to 1000 cm -1 ; these regions correspond to the phenyl ring bond in lignin and the C-H bond in cellulose and hemicellulose, respectively (Li et al 2012;Sundari and Ramesh 2012). The wavenumber around 3340 cm -1 was assigned to hydrogen bonded (O-H) stretching absorption.…”

Water hyacinth (Eichhornia crassipes) is an invasive floating plant that has caused many environmental problems in Asia. Efficiently removing and utilizing this biomass has become an urgent issue. In this work, the composition of water hyacinth biomass (WHB) was analyzed with the Van Soest method. The combined cellulose and hemicellulose content reached 58.6%, and the lignin content was very low compared with other biomass. An efficient alkali pretreatment technology for WHB was developed, and the enzymatic hydrolysis of WHB to reducing sugars was investigated. With favorable hydrolysis conditions for the alkali-pretreated WHB, the cellulose conversion rate reached almost 100%. Structural changes resulting from WHB pretreatment and hydrolysis were analyzed by Fourier-transform infrared spectrometry and scanning electron microscopy. This work demonstrates that WHB is an alternative cellulose source for bioenergy production.
