“…For example, Zhang et al 26 used vinyltrimethoxysilane to hydrophobically modify hydrolyzed cellulose nanofibers extracted from kapok, resulting in fibers with superhydrophobicity and a CA of 150.5° (Figure 3a). Wang and Liu 30 used methyltrimethoxysilane to make dissolved and freeze‐dried cotton fibrous aerogels superhydrophobic, with CA greater than 154°.…”

“…Furthermore, the diameter of a KF is too small, and it has poor mechanics, making it difficult to spin and apply widely. However, KFs have attracted increasing attention due to their excellent adsorption abilities. − These can be ascribed to their distinct hollow structures and hydrophobic properties. The excellent water repellency of the wax on the surface of a hollow fiber causes it to float on water and difficult to wet.…”

The superhydrophobic surface and slippery liquid-infused porous surface (SLIPS)/lubricant-infused surface (LIS) have attracted increasing attention owing to their multifunctionality. However, their practical applications face several problems such as complex and inefficient preparation technology, loss of lubricant, and fragile microstructures. Therefore, new strategies for preparing microstructures must be developed for constructing superhydrophobic and lubricant-infused coatings. Herein, a low-cost and high-efficiency method for developing superhydrophobic and lubricant-infused coatings based on in situ grown TiO2 on the surface of a hollow kapok fiber (KF) is reported. The anti-icing, antifouling, and anticorrosion performance of the superhydrophobic and lubricant-infused coatings are compared. The superhydrophobic coating reduces the formation and accumulation of ice. The lubricant-infused coating exhibits an extremely low ice adhesion strength and durable anti-icing properties. The superhydrophobic and lubricant-infused coatings show the outstanding antifouling property of diatom; the superhydrophobic surface exhibits superior stability over LIS without an external force field. The lubricant-infused coating shows excellent corrosion resistance and durability when immersed in a 3.5% NaCl solution. The superhydrophobic coating loses its protection as a result of the corrosion media permeating the metal substrate via the electrolytic cell and coating interface, and the lubricant-infused coating provides lasting corrosion resistance because of the lubricant filling into the interface. Although the superhydrophobic coating is fragile and the lubricant-infused coating will lose lubricant, this simple and convenient approach can be repeated to keep the coatings active. This study provides new inspiration for the fabrication of superhydrophobic surfaces and LIS based on natural products.

Cattail cellulose microfibers were produced through a sequence of hydrothermal (HTP) and sodium hydroxide (NaOH) pretreatments, followed by the synthesis of deep eutectic solvent (DESs). This study focuses on assessing the oil-adsorption capacity of these microfibers and explores the preparation of optimized adsorbent materials. The optimization involves DESs synthesis at temperatures of 50, 70, and 90°C, following a two-stage pretreatment process, including HTP at 180°C for 2 h and NaOH treatment at 90°C for 1 h, with an emphasis on maximizing cellulose content, hemicellulose removal, and delignification. Various oil absorption tests were conducted using the resulting absorbent materials under suitable conditions. The findings highlight that the optimal temperature for DESs synthesis is 70°C, resulting in microfibers with a composition of 43.13% cellulose, 3.88% hemicellulose, and 8.6% lignin. These absorbent materials exhibit a remarkable oil absorption capacity, capable of absorbing a variety of oils at a consistent rate of approximately 6–7 g/g. Notably, these cellulose fiber materials outperform conventional oil-absorbing materials while utilizing environmentally abundant cattails.
