A green and environmental benign method to extract cellulose nanocrystal by ball mill assisted solid acid hydrolysis

Chitosan Hydrogels Crosslinked by Genipin and Reinforced with Cellulose Nanocrystals: Production and Characterization

“…These values are comparable to those obtained by Shaheen et al [25], who reported lengths and diameters ranging from 140 to 423 nm and 21 to 47 nm, respectively. Besides that, the results are also similar to the results obtained with CNC produced by other processes, such as acid hydrolysis with oxalic acid solution, through which Song et al [26] obtained CNC with the same needle-like morphology with length and diameter around 300 nm and 10 nm, respectively. By using phosphoric acid solution, Wang et al [27] obtained CNC with lengths ranging from 100 to 330 nm and diameter ranging from 2 to 6 nm.…”

Fabrication of Multifunctional Filters via Online Incorporating Nano‐TiO2 into Spun‐Bonded/Melt‐Blown Nonwovens for Air Filtration and Toluene Degradation

“…Spectrum a) shows the TiO 2 characteristic peak from 450 to 700 cm −1 due to TiO stretching vibration . Spectrum b) presents obvious CH symmetric and anti‐symmetric stretching vibration peaks at 2958, 2929, and 2847 cm −1 , CH deformation little peak of the aromatic ring at around 1018 cm −1 , CO stretching vibration peaks at 1723 cm −1 , CH bending vibration at 1460, 1377, and 1340 cm‐ 1 , and CH wagging vibration peak at 1167 and 974 cm −1 , indicating the existence of PP, PE, and PET in the SM nonwovens. Due to PE/PET sheath/core structure, PET characteristic peak at 1018 was weak.…”
