“…Water absorption performance is a critical parameter for cellulose hydrogels, particularly when utilized as moisture-absorbing materials or in drug delivery systems [ 110 , 111 , 112 , 113 , 114 ]. This performance is influenced by factors such as cross-linking density [ 115 ], pore structure [ 116 ], and the hydrophilicity of the material [ 116 ], influencing the water absorption performance, typically measured by water absorption rate [ 117 ] and water content [ 118 ], which reflect the gel’s ability to absorb and retain moisture.…”

Cellulose hydrogels, formed either through physical or chemical cross-linking into a three-dimensional network from cellulose or its derivatives, are renowned for their exceptional water absorption capacities and biocompatibility. Rising demands for sustainable materials have spurred interest in cellulose hydrogels, attributed to their abundant supply, biodegradability, and non-toxic nature. These properties highlight their extensive potential across various sectors including biomedicine, the food industry, and environmental protection. Cellulose hydrogels are particularly advantageous in applications such as drug delivery, wound dressing, and water treatment. Recent large-scale studies have advanced our understanding of cellulose preparation and its applications. This review delves into the fundamental concepts, preparation techniques, and current applications of cellulose hydrogels in diverse fields. It also discusses the latest advances in nano-lignin-based hydrogels, providing a comprehensive overview of this promising material and offering insights and guidance for future research and development.

“…1, contain both anionic and cationic hydrophilic groups in the same molecule [6]. The hydrophilic groups make it easier to form O/W emulsions and maintain better stability [7][8][9]. Amphoteric surfactants usually have good detergent, dispersing, emulsifying, sterilizing, ber-softening, and antistatic properties, and therefore they have a wide range of applications in many elds [10].…”

In industries, emulsions must adapt to various acid-base environments, making it crucial to study their properties and acid-base resistance. We prepared an oil-in-water (O/W) emulsion by adding oleic acid and polyether amine D-230 to water, with tetradecane as the oil phase. The stability of the emulsion was assessed by measuring the interaction forces between droplets using optical tweezers. Our results demonstrated that the amphoteric surfactant could significantly improve the stability of the emulsion. The results show that in the presence of amphoteric surfactant, the maximum repulsion force between droplets can reach 18.9 pN and ζ- potential is -65.16 mV, while in the absence of surfactant, the maximum repulsion is only 1.2 pN and ζ- potential is -25.54 mV. Further stabilization was achieved with the addition of 10 mmol/L anionic surfactant sodium dodecyl sulfate (SDS) or 1 mmol/L cationic surfactant cetyltrimethyl ammonium bromide (CTAB). With SDS, the maximum repulsive force was 40.8 pN and ζ- potential was 132.44 mV at the drop distance of 1.93 µm. With CTAB, the maximum repulsive force of 48.2 pN and ζ- potential of + 42.28 mV were measured at the drop distance of 3.12 µm, indicating that adding surfactants can effectively improve the stability of the emulsion. At the same pH value, the combined emulsion can measure the interaction force at a longer drop distance than the emulsion containing only amphoteric surfactants. When pH = 8, the interaction force of 1 mmol/L CTAB and 10 mmol/L SDS can be measured at the drop distance of 2.51 µm and 2.78 µm, respectively. Only the emulsion containing amphoteric surfactant can be measured at the drop distance of 2.26 µm, and the results show that it can enhance the acid-base resistance of the emulsion. These emulsions can be used to make good anticorrosive coatings and improve various properties of the original coatings.
