Fabrication of lignin-containing cellulose bio-composite based on unbleached corncob and wheat straw pulp

All-cellulose composites fabricated by in-situ welding

“…As shown in the C1s spectra (Figs. 3(b) and (c)), there was an increase of C1 and decrease of C2 contents, which could indicate that there are fewer hydroxyl groups on the surface of ACCs than that on the surface of FP because of the transformation from cellulose I to cellulose II (Hao et al 2019;Hu et al 2021a;Yu et al 2022). Moreover, the O/C ratio also changed (Table 1).…”

“…Moreover, compared with the FP, the ACCs underwent some transformation. It can be directly perceived that a lot of nanocellulose fibers were present on the surface and the cross-section of ACCs, constituting the unique intertwined structure of microfibers and nanofibers(Yousefi et al 2015;Hu et al 2021b;Nemoto and Nakamata 2021;Bian et al 2022;Yu et al 2022).…”

Comprehensive Study of Preparation of Carboxy Group-Containing Cellulose Fibers from Dry-Lap Kraft Pulps by Catalytic Oxidation with Solid NaOCl

“…Cellulose, the most abundant plant biomass on Earth, has attracted great attention as an ideal alternative to petroleum-based materials to tackle environmental pollution and energy crises for a sustainable future. − Plant cellulose fibers can be obtained from abundant natural plants, such as trees, bamboo, reeds, and sugar cane, by chemical pulping and successive multistage bleaching processes. − Cellulose-based materials are biodegradable, renewable, and have excellent optical and mechanical properties, and they have wide current and potential applications in paper, buildings, optoelectronics, and bioengineering . Chemical reactions of cellulose are promising conversion methods to add new functionalities to native cellulose fibers. − However, native cellulose fibers are stable and usually require large amounts of chemicals and solvents at high temperatures for long times to sufficiently introduce new groups into cellulose molecules such as ester or ether substituents.…”
