“…Oil sorption tests showed that the OTS-functionalised samples were able to absorb oils and organic solvents with a sorption capacity of (185 ± 8)%, (229 ± 3)%, (289 ± 6)% and (309 ± 7)% for rapeseed oil, dioxane, silicone oil and chloroform, respectively (Figure 4a). These values are similar to those reported for other natural fibrous materials, such as loofah sponges modified with fluorinated silica nanoparticles (~300% for chloroform) [10], hydrophobic cotton fibres (~500% for vegetable oil) [43] and coir fibres (180–540% for crude oil) [44]. The possibility to recycle and reuse the OTS-treated samples was evaluated by sorption/purification cycles.…”

“…They are formed of a three-dimensional (3D) network of cellulose-based microfibres [8]. Polyhedral oligomeric silsesquioxane [9], fluorinated silica nanoparticles [10] and waterborne polyurea adhesives containing silica nanoparticles [11] have been used to functionalise Luffa sponges. The treated sponges were characterised by a water contact angle (WCA) between 152° and 156°, and an oil absorption capacity (diesel, vegetable oil, chloroform and toluene) in the range of 3–10 g/g.…”

Porous materials derived from natural resources, such as Luffa sponges, pomelo peel and jute fibres, have recently emerged as oil adsorbents for water purification, due to their suitability, low environmental impact, biodegradability and low cost. Here we show, for the first time, that the porosity of the fruiting body of polypore mushrooms can be used to absorb oils and organic solvents while repelling water. We engineered the surface properties of Ganoderma applanatum fungi, of which the fruiting body consists of a regular array of long capillaries embedded in a fibrous matrix, with paraffin wax, octadecyltrichlorosilane (OTS) and trichloro(1H,1H,2H,2H-perfluorooctyl)silane. Morphological and wettability analyses of the modified fungus revealed that the OTS treatment was effective in preserving the 3D porosity of the natural material, inducing super-hydrophobicity (water contact angle higher than 150°) and improving oil sorption capacity (1.8–3.1 g/g). The treated fungus was also inserted into fluidic networks as a filtration element, and its ability to separate water from chloroform was demonstrated.

“…In order to determine the wettability of a surface, contact angle measurements and contact angle hysteresis, with a variety of different liquids, are often investigated [37]. The wetting of these specialized coatings can range from hydrophobic to hydrophilic, oleophobic to oleophilic, or omniphobic to omniphilic [38,39]. Furthermore, a surface can display extreme or super-repellency towards a liquid, for example superhydrophobicity, if the contact angle is greater than 150° and the hysteresis is lower than 5° [40].…”

Since initially being reported, fluorinated silica nanometer-sized particles (F-SiNPs) have gained much interest in the scientific community, due to their unique properties. These properties, include, low surface energies, increased mechanical strength, thermal robustness, and chemical resistance, and are a direct result of the incorporation of fluorine with a nanometer-sized silica network. This review aims to summarize the synthetic methods that have, and are still, being utilized to prepare these specialized materials. Following this, applications for F-SiNPs, with an emphasis on recent examples, will be presented in further detail.

“…Also there were reports about the use of lignin‐cellulosic sponge material for the absorption of oil and organic solvents from water, but the synthesis of such lignin based materials requires multistep procedures and by the use of harsh chemicals like NaClO 2 , silane, fluorinating agents etc. Hence the feasibility and sustainability of the process are missing.…”

Biomass‐Derived Lignocellulosic Graphene Composite: Novel Approach for Removal of Oil and Organic Solvent

et al. 2019

View full text Add to dashboard Cite

Novel approach to develop a biomass derived lignin‐cellulose based, ultra‐light, hydrophobic graphene supported spongy composite was synthesized to absorb oil and organic solvents from wastewater. Spongy composite was synthesized by a facile and highly efficient one‐pot hydrothermal method from the natural precursor. Lignin‐cellulose functionalized graphene (LCG) sponge was synthesized from graphene oxide (GO) and sugarcane waste powder (SCwP) in presence of natural latex. LCG successfully demonstrated separation of oil from oil‐water mixture. LCG has high oil sorption capacity in the range of 25–50 g of oil per gram of sorbent. This material showed high efficiency as a sorbent to separate organic chemicals from wastewater. The absorption capacity of LCG sponge was enhanced thrice in comparison with SCwP and could be reused up to 10 cycles. The continuous oil water separation process was demonstrated using LCG sponge from the oil‐water mixture, which can be applied for large scale oil recovery from the waste stream.
