“…The difference in the S/G ratio might due to the different morphological regions for each wood (7). The higher proportion of β-O-4 ′ substructures is advantageous to the successive depolymerization and amelioration of lignin (28,29). Thus the D. sinicus could serve as efficient feedstock for biorefinery industries (30,31).…”

Milled wood lignin (MWL) was isolated from Dendrocalamus sinicus, an abundant bamboo variety in the earth, using Bjorkman method. Elucidation and quantification of the chemical structures for the isolated MWL have been facilitated by employing FT-IR and NMR techniques. The obtained results showed that the MWL consists of syringyl (S), guaiacyl (G), and p-hydroxyphenyl (H) units, indicating it as grass type (HGS) lignin. There is no significant change in structure (i.e. cleavage at α-O-4 ′ and β-O-4 ′ linkage) was observed. NMR techniques indicated that the isolated lignin was rich in β-O-4 ′ aryl ether substructures and syringyl (S) units. Furthermore, the sufficient understanding of the chemical structure of the lignin benefits their effective utilization towards the production of renewable biomass and biofuels.

“…Previous MFLC studies are commonly either based on a specific wood starting material (i.e. wood flour or specific pulp fibres) (Abe et al 2009;Herzele et al 2016;Osong et al 2013;Rojo et al 2015;Yousefi et al 2013), specific chemical treatments (Herrera et al 2018;Herzele et al 2016) or non-wood biomass (Jiang et al 2019;Lu et al 2018;Peng et al 2018;Yousefi et al 2018). Here, the focus is on commercially available unbleached Kraft fibres as a source, and the investigation is systematic on effects of processing and lignin content on structure and composition of the corresponding MFLC grades.…”

Microfibrillated cellulose (MFC) is an important industrial nanocellulose product and material component. New MFC grades can widen the materials property range and improve product tailoring. Microfibrillated lignocellulose (MFLC) is investigated, with the hypothesis that there is an optimum in lignin content of unbleached wood pulp fibre with respect to nanofibril yield. A series of kraft fibres with falling Kappa numbers (lower lignin content) was prepared. Fibres were beaten and fibrillated into MFLC by high-pressure microfluidization. Nanosized fractions of fibrils were separated using centrifugation. Lignin content and carbohydrate analysis, total charge, FE-SEM, TEM microscopy and suspension rheology characterization were carried out. Fibres with Kappa number 65 (11% lignin) combined high lignin content with ease of fibrillation. This confirms an optimum in nanofibril yield as a function of lignin content, and mechanisms are discussed. MFLC from these fibres contained a 40-60 wt% fraction of nanosized fibrils with widths in the range of 2.5-70 nm. Despite the large size distribution, data for modulus and tensile strength of MFLC films with 11% lignin were as high as 14 GPa and 240 MPa. MFLC films showed improved water contact angle of 84-88°, compared to neat MFC films (\ 50°). All MFLC films showed substantial optical transmittance, and the fraction of haze scattering strongly correlated with defect content in the form of coarse fibrils.

“…), banana, jute, pineapple(Abraham et al 2011), triticale straw(Tarrés et al 2017), sunflower stalks(Ewulonu et al 2019), bamboo chips(Lu et al 2018) and even bark(Chen et al 2019) are some of the recently investigated examples. Additionally, many research groups have been working on the isolation, characterization, and application of LCNFs from wood sources Wang et al (2012).…”

On the potential of lignin-containing cellulose nanofibrils (LCNFs): a review on properties and applications

2019

View full text Add to dashboard Cite

This review outlines the present state and recent progress in the area of lignin-containing cellulose nanofibrils (LCNFs), an emerging family of green cellulose nanomaterials. Different types of LCNF raw materials are described, with main focus on wood-based raw materials, and the properties of the resulting LCNFs are compared. Common problems faced in industrial utilization of CNFs are discussed in the light of potential improvements from LCNFs, covering areas such as chemical and energy consumption, dewatering and redispersibility. Out of the potential applications, barrier films, emulsions and nanocomposites are considered.
