“…It was due to the high viscosity oils would block the porous structure of modified sponge. Although reusing times of ZSSiOsp were less than synthetic polymer oil absorbing materials (Gao et al, 2018; Tan & Zhang, 2022; Wang, Sun, et al, 2021), its natural polymers (zein and SA) were eco‐friendly.…”

In order to effectively promote the treatment of pollution containing organics or crude oil, many oil‐absorbing materials were explored. However, most of them were synthetic polymers, which was difficult to be decomposed and easily cause secondary pollution. In this study, zein and sodium alginate (SA), two cheap natural polymer materials, were used as eco‐friendly and biodegradable biomass materials; a novel porous biomass‐based sponge (ZS‐PBSp) was synthesized. Then, by impregnating with SiO2 nanoparticle (nano‐SiO2) and octadecanethiol (OCT), the modified porous sponge (ZSSiOsp) was obtained. ZSSiOsp was characterized by scanning electron microscopy (SEM), infrared (IR), X‐ray diffraction (XRD) and thermogravimetric analysis (TGA) and applied to adsorb organics, such as organic solvents, petroleum products and cooking oil. It indicated that the surface of ZSSiOsp was rough, and its water contact angle (WCA) increased to 131.5°. ZSSiOsp effectively adsorbed organics, its absorption capacity got to 115.7% for chloroform and 77.6% for rapeseed oil, respectively. It also effectively separated oily substances from oil–water mixture. In summary, the obtained ZSSiOsp was an eco‐friendly material for oil absorption and separation, which was a kind of promising candidate in water treatment and environmental protection.

“…The absorption capacity of the hydrophobic/oleophilic cellulose aerogel for oil and organic solvents was on a moderate level, higher than some oil absorption materials such as PDMS sponge 54 and PVDF-MWCNT foam, 11 but lower than some others such as cellulose aerogel modified by vapor deposition method 42 and polymer sponge. 55 Nevertheless, the hydrophobic/oleophilic aerogel prepared in this work had its own unique advantages. The preparation method was simple, cheap and environmentally friendly, which made it advantageous in practical applications.…”

A cellulose aerogel with very low overall density is fabricated by freeze‐drying aqueous cellulose solution. A hydrophobic/oleophilic cellulose aerogel is further fabricated by coating the cellulose aerogel with hexyltrimethoxysilane‐modified SiO2 nanoparticles. The features of the developed hydrophobic/oleophilic cellulose aerogel are characterized with density and porosity measurement, infrared spectroscopy, X‐ray photoelectron spectroscopy, scanning electron microscopy, and contact angle measurement. Finally, the oil absorption performance of the developed hydrophobic/oleophilic cellulose aerogel is investigated. The results show that SiO2 nanoparticles have been successfully loaded on the surface of the aerogel backbone after fulfillment of fabrication, and the surface of the aerogel turns to be hydrophobic/oleophilic (water contact angle 131° and oil contact angle 0°). The oil absorption experiment results show that the absorption capacity for organic solvents is from 10 to 21 times the initial aerogel weight, depending on the density of the absorbed organic solvents. In addition, the aerogel still maintains good stability in high temperature, strong acid or strong base conditions. Furthermore, the aerogel also shows good performance in separating oil from oil–water mixtures. This hydrophobic/oleophilic cellulose aerogel can be a promising choice for remedying water pollution caused by oil contamination.

“…Thus, it is essential to modify MS to be hydrophobic for the separation of oil−water mixtures. For example, Tan and Zhang 19 constructed a hydrophobic melamine sponges modified with polydopamine/3-mercaptopropyltrisiloxane (PDA/SH-3Si) for oil−water separation. The modified MS sponges showed high hydrophobicity (139.3°) and outstanding ability to absorb a variety of oil−water mixtures.…”

Hydrophobic sponges have attracted significant interest in oil spills and water−oil separation as potential absorption materials due to their desirable absorptivity, selectivity, and elasticity. In this paper, a hydrophilic melamine sponge (MS) is transferred into a superhydrophobic sponge via polydimethylsiloxane (PDMS) modification followed by in situ growth of fluorine-functionalized covalent organic framework (denoted as TFA-COF) nanoparticles. Therefore,
