Summary: In this study, hydrophobic cellulose aerogels were prepared for oil-water separation by modifying regenerated cellulose aerogels with vapour phase deposition. Cotton pulpboard was dissolved in a NaOH/urea/water system and cross-linked with N,N-methylene bisacrylamide (MBA) to obtain a hydrogel. The hydrogel was freeze-dried to form a regenerated cellulose aerogel. The regenerated cellulose aerogels were further modified with Metyltrimethoxysilane (MTMS) and Fe3O4 nanoparticles to produce magnetic hydrophobic regenerated cellulose aerogels. These aerogels exhibited high oil/water absorption and selectivity, and can be recycled multiple times without significant decrease in adsorption capacity.

Summary: The hydrophobicity of cellulose can be significantly increased through acid hydrolysis and esterification. Esterification disrupts the crystalline structure of cellulose, replacing polar hydroxyl groups with non-polar substituents to enhance the hydrophobicity. Increasing the number of non-polar groups in the ester substituent contributes to the rise in hydrophobicity of cellulose derivatives.

Summary: This study evaluated the effect of cryogrinding, a relatively new, cost-effective, and sustainable mechanical treatment method, on the physicochemical properties of different types of cellulose fibers. The results showed that cryogrinding can improve the properties of cellulose, particularly by reducing its degree of polymerization, indicating the potential of this technique in cellulose processing.

Summary: The objective of this study was to obtain materials with aromatherapeutic and antibacterial properties by applying emulsions based on peppermint essential oil (PEO) onto cotton fabric. Different emulsions based on PEO incorporated in various matrices were prepared and the stability of the emulsions was evaluated. The materials treated with the stable emulsions were analyzed for sensory activity, comfort characteristics, and gradual release of PEO. The results showed that materials treated with emulsions had good inhibitory effects on S. aureus and E. coli, suggesting the potential of using peppermint-oil-based emulsions for aromatherapeutic patches, bandages, and dressings with antibacterial properties.

Summary: In this study, cellulose and graphene oxide (GO) were crosslinked together using a simple and environmentally friendly silane crosslinking method, forming a cellulose/GO hybrid membrane. The hybrid membrane exhibited good thermal stability, strong hydrophobicity, self-cleaning properties, controllable Joule heating capability, extremely fast thermal response, and good electrothermal stability. It showed great potential in future multi-functional electronic products such as electric heating electronic devices, sensors, and smart clothing.

Summary: Engineering the surface chemistry allows precise control of interfacial interactions, which is crucial for fabricating superior antifouling coatings and separation membranes. In this study, a hydrophobic chain engineering strategy is presented to regulate the membrane surface at a molecular scale. By sequentially assembling hydrophilic phytic acid and hydrophobic perfluorocarboxylic acids on a graphene oxide membrane, an amphiphilic surface is formed. The surface energy is reduced by introducing perfluoroalkyl chains, while the surface hydration can be tuned by changing the hydrophobic chain length, optimizing both fouling-resistance and fouling-release properties synergistically.

Summary: In this study, we successfully developed a reusable, low cost and biodegradable oil absorption material with high capacity. A hydrophobic cellulose sponge was constructed from cellulose xanthate by regenerating cellulose and surface silanization using methyl trichlorosilane. The sponge demonstrated high porosity up to 87.46%, which could be regulated with p-Toluenesulfonyl hydrazide. It exhibited excellent structure stability, fully recovering from 90% compression strain and showing high durability (60 cycles at 90% stain). With its hydrophobic surface, the sponge displayed a high absorption capacity of over 30 times its weight for oils and organic solvents, indicating promising applications in oil and water separation.
