“…Charged cellulose nanofibrils can absorb and retain water due to the ionic osmotic pressure. ,, Therefore, swelling of adhesives prepared only with charged CNFs can cause a significant mechanical property loss, impairing their performance, since penetration of water molecules dissociates hydrogen bonds among the nanofibers . Several strategies increase the strength of cellulosic materials in water or high-humidity environments, including covalent bonds − and noncovalent interactions. − Here, we propose a simple mixing method for oppositely charged particles in water to overcome this issue.…”

Adhesives prepared with renewable materials through environmentally friendly processing offer an appealing alternative to their petroleum-based counterparts. Herein, we evaluated the adhesive properties of cationic cellulose nanofibrils (CCNFs) under dry and wet conditions and after mixing with natural rubber latex (NRL). Uniaxial tensile tests of negatively charged substrates (paper, aluminum (Al), and polypropylene (PP)) bonded with CCNF show a maximum lap shear strength that approached the failure point of the substrates, indicating the formation of a robust adhesive joint. The wet adhesion of CCNFs was improved (53% for PP and 154% for Al) by simple aqueous mixing with NRL suspension. This straightforward methodology promotes controlled CCNF and NRL electrostatic assembly that reduces the swelling of nanofibrils by water and improves adhesive cohesion. Cryogenic transmission electron microscopy images of CCNF/NRL complexes reveal that NRL particles are coated by a fibrillar CCNF network, providing morphological evidence that cationic nanofibrils contribute to interfacial adhesion to the solid substrates, while NRL enhances water resistance. This study presents a simple method to control noncovalent interactions and prepare nanocellulosebased adhesives with good mechanical properties and improved water resistance that are suitable for developing adhesives for different fields.

“…Notably, after the introduction of cations, the characteristic peaks of the ester group and ether bond of both SC-Ca-N3 and SC-Ca-G3 were significantly enhanced. This suggests that cationic synergistic can effectively promote the esterification–etherification double cross-coupling reaction [ 28 , 29 ].…”

Crosslinking is a promising method to modulate the gel properties of food-grade starch gels. Still, the poor crosslinking effect of a single type of crosslinker limits the application of this method in starch gel modification. In this study, an Ca2+ synergistic multiple crosslinking modification method was proposed to prepare crosslinked starches with good gel properties and setting. The rheological properties of the samples were tested. The modified sample (SC-Ca-N3, G′ = 1347 ± 27) showed a 79% improvement compared to the starch without synergistic crosslinking modification (SC-N, G′ = 752 ± 6). The elastic modulus of starch gels can be adjusted by changing the degree of the crosslinking reaction. The results of nonlinear rheological Lissajous curve analysis showed that the synergistically crosslinked gel system strongly resisted deformation. In addition, the microstructure of the modified samples was characterized using scanning electron microscopy. The XPS, FTIR, and XRD results indicated that multiple molecular forces participate in the synergistic crosslinking reaction.

“…Among the available technologies, adsorption is considered to be the most competitive, offering easy operation, relatively low costs, and non-toxic byproducts [ 251 , 252 ]. Cellulose-based aerogels are recognized as potential candidates for wastewater treatment due to cellulose’s renewable and biodegradable nature, easily functionalized properties, unique 3D network structure, and high surface area [ 246 , 253 , 254 , 255 ]. However, challenges remain, including avoiding toxic crosslinking agents and achieving a balance between high adsorption capacity and selectivity [ 246 , 256 ].…”

Given their exceptional attributes, aerogels are viewed as a material with immense potential. Being a natural polymer, cellulose offers the advantage of being both replenishable and capable of breaking down naturally. Cellulose-derived aerogels encompass the replenish ability, biocompatible nature, and ability to degrade naturally inherent in cellulose, along with additional benefits like minimal weight, extensive porosity, and expansive specific surface area. Even with increasing appreciation and acceptance, the undiscovered possibilities of aerogels within the textiles sphere continue to be predominantly uninvestigated. In this context, we outline the latest advancements in the study of cellulose aerogels’ formulation and their diverse impacts on textile formations. Drawing from the latest studies, we reviewed the materials used for the creation of various kinds of cellulose-focused aerogels and their properties, analytical techniques, and multiple functionalities in relation to textiles. This comprehensive analysis extensively covers the diverse strategies employed to enhance the multifunctionality of cellulose-based aerogels in the textiles industry. Additionally, we focused on the global market size of bio-derivative aerogels, companies in the industry producing goods, and prospects moving forward.
