“…This was due to the introduced aldehyde groups reducing the number of hydroxyl groups that could interact with water molecules. This result is in agreement with earlier reports that found hydrophobicity increased when the aldehyde group was introduced [47].…”

Two types of cellulose nanofibrils (CNFs) were isolated from cotton linter fibers and hardwood fibers through mechanical fibrillation methods. The dialdehyde cellulose nanofibrils (DACNFs) were prepared through the periodate oxidation method, and their morphological and structural properties were investigated. The characteristics of the DACNFs during the concentration process were also explored. The AFM analysis results showed that the mean diameters of wood fiber-based CNFs and cotton fiber-based CNFs were about 52.03 nm and 69.51 nm, respectively. However, the periodate oxidation treatment process obviously reduced the nanofibril size and destroyed the crystalline region of the nanofibrils. Due to the high crystallinity of cotton fibers, the cotton fiber-based DACNFs exhibited a lower aldehyde content and suspension stability compared to the wood fiber-based DACNFs. For the concentration process of the DACNF suspension, the bound water content of the concentrated cotton fiber-based DACNFs was lowered to 0.41 g/g, which indicated that the cotton fiber-based DACNFs could have good redispersibility. Both the wood fiber-based and cotton fiber-based DACNF films showed relatively good transmittance and mechanical strength. In addition, to the cotton fiber-based DACNF films had a very low swelling ratio, and the barrier water vapor and oxygen properties of the redispersed cotton fiber-based DACNF films decreased by very little. In sum, this study has demonstrated that cotton fibers could serve as an effective alternative to wood fibers for preparing CNFs, and that cotton fiber-based DACNFs have huge application prospects in the field of packaging film materials due to their stable properties during the concentration process.

“…The reason was that the hydrogen bonds between cellulose molecules were sensitive to water and were broken by water molecules, leading to a decrease in tensile strength. 55 LRCF and LDCF exhibited better levels of wet tensile strength of 31.0 and 33.3 MPa, respectively, which were numerically very close (no significant difference). However, their depletion in water was 61.4 and 63.1%, respectively.…”

The mass consumption of plastic straws already seriously causes environmental pollution and harms human health, which urgently requires the manufacture of eco-friendly straws as alternatives. Herein, a facile approach was reported for producing tough, water-resistant, and biodegradable lignocellulose straws. The renewable agricultural residue (i.e., rice stalk) was pretreated with a deep eutectic solvent to redistribute lignin from the stalk fibers and obtain two cellulosic materials: lignin-regenerated cellulosic fiber (LRCF) and lignin-dissolved cellulosic fiber (LDCF). The LRCF and LDCF were refined and fibrillated and subsequently utilized to form a wet film. The wet film was then rolled into a tube without any adhesives and dried as straw products. The obtained straws exhibited excellent mechanical properties (maximum tensile strength and toughness of 90.2 MPa and 15.3 MJ/m 3 , respectively), water resistance (maximum water contact angle of 95.34°), and natural biodegradability (the fastest complete degradation in 25 days). These straws are fully derived from lignocellulose biomass and provide environmentally friendly alternatives to plastic straws.
