“…Wood fiber is the most prevalent industrial source of MCC. Renewable resources that can be utilized to manufacture MCC include coir fiber (Gichuki et al, 2022), oil palm empty fruit bunches (Krishnan et al, 2022), cotton fibers (Do et al, 2022), nata de coco (Nurhadi et al, 2022), birch wood (Tarabanko et al, 2022), flax (Tkachenko et al, 2022), sunflower seed waste (Akatan et al, 2022), and Lagenaria siceraria fruit (Asif et al, 2022). The physical properties of cellulose and MCC are taken from different plants, and their parts vary in water absorbability, polymerization, porosity, and crystallinity (Asif et al, 2022).…”

The large amount of paper sludge generated from wastepaper industries emphasizes the importance of developing green waste management. The study aimed to characterize microcrystalline cellulose from paper sludge using different acid concentrations. The properties of chemical composition, morphological, thermal, reflectance, and crystallinity index were accessed. The disappearance of peaks in FTIR was related to the removal of amorphous structure. SEM confirmed the reduction in diameter with the decomposed temperature of 266°C. 3.0 M reflects the highest UVB at 28% and UVA at 39% due to the highest crystallinity index of 31%, which is possible for reinforcement application in film packaging.

“…Cellulose is a rich natural resource. Approximately 7 billion tons are produced every year and it is widely used in numerous elds, such as ltration mats, wound dressings, drug-controlled release systems, and food llers (Do et al 2022;Liu et al 2022;Tu et al 2022). Because cellulose has low density, high speci c surface area, and contains a large number of hydroxyl groups, it is widely used as lter materials (Santos et al 2022;Vishwanath et al 2022).…”

Cellulose has been widely used in filtration owing to its abundance, low density, and high specific surface area. However, the use of cellulose-based scaffolds for filtration under high temperatures or with sparks is difficult to realize because cellulose is highly flammable. To develop an advanced cellulose-based filtration material with excellent flame-retardant and filtration performance, in this study, an ice template is employed to prepare a cellulose/expandable graphite (EG) aerogel with a direction porous structure for filtration. The effect of the EG concentration in the aerogel on the aerogel’s physical properties, as well as its flame-retardance and filtration performance is investigated. Experimental data indicates that a compound aerogel with a 30 wt% EG concentration is extinguished immediately after leaving the fire source and has a self-extinguishing time as short as 0.155 s. The formation of a direction porous structure in cellulose/EG aerogels provides a pathway for air movement during the filtration process. The use of EG could improve the filtration performance of cellulose aerogels by increasing the specific surface area. When the EG concentration in the aerogel is 30 wt%, the blocking efficiency of particle sizes less than 0.3 and 0.5 µm reaches 98 % and 99 %, respectively, and the blocking efficiency of particle sizes less than 1.0 µm is 96 %. As-prepared cellulose/EG aerogels have good mechanical properties and thermal stability, which implies that they can be used for filtration under high temperatures and sparks. Moreover, the filtration performance of cellulose/EG aerogels prepared using ice templates with direction porous structure and excellent flame-retardance can potentially be used for filtration-based applications under high temperature and electrical spark conditions. The use of EG and direction porous structures in cellulose aerogels provides a novel idea for the functionalization of cellulose scaffolds.

Hydrogels are notable for their outstanding absorbent qualities, satisfactory compatibility with biological systems, ability to degrade, and inherent safety, all of which contribute to their high demand in the field of biomedicine. This study focuses on the fabrication of hydrogels using environmentally friendly cellulosic material. Cellulose hydrogel beads were prepared by physical cross‐linking in a NaOH/urea medium. Furthermore, nano polydopamine was integrated into the hydrogel matrix as functional polymers and α‐mangostin was employed as an active pharmaceutical ingredient. The physicochemical properties were comprehensively analyzed using Fourier‐transform infrared spectrometer, 13C cross‐polarization/magic angle spinning nuclear magnetic resonance, thermogravimetric analysis, and scanning electron microscope. The drug delivery properties, including water content, swelling ratio, and drug release profiles, were evaluated. In vitro cytotoxicity against MC3T3‐E1 cells was assessed using sulforhodamine B staining. All test hydrogels exhibited inhibitory activity against the growth of MC3T3‐E1 cells. These results indicated the potential use of these hydrogels as a drug delivery carrier for α‐mangostin in the treatment of ankylosing spondylitis.
