Summary: By using a simple two-step dipping method, an environmentally friendly and durable modified melamine sponge with superhydrophobic properties was fabricated. The sponge, named MS/rGO/AC/PDMS, has a multi-stage pore structure due to the fixation of active carbon and reduced graphene oxide on the melamine sponge skeleton with polydimethylsiloxane glue. The as-prepared sponge showed excellent water repellency with a water contact angle of up to 164 degrees. Used for oil/water separation, MS/rGO/AC/PDMS demonstrated outstanding oil-water selectivity, high oil sorption ability (up to 120 g/g), and separation efficiency over 99.85%.

Summary: Water is a crucial resource for biological and social development. Oily wastewater pollution has become a serious global challenge. Researchers have successfully fabricated a bamboo cellulose foam with special wetting characteristics and excellent oil-absorption performance using a simple and environmentally friendly method. The foam has a high oil absorption capacity and recyclability, as well as resistance to acid and alkali corrosion. Due to the biodegradable and low-cost nature of bamboo cellulose, this superhydrophobic/superoleophilic foam has great potential for oily wastewater treatment.

Summary: SHSO membranes have shown high efficiency in selectively separating oil from oil-water mixtures, but their stability under acid and alkaline environments, as well as the adsorption of heavier components of crude oils, still require further research. Additionally, the fouling performance of SHSO membranes in water-derived fouling has not been well studied in oil-water separation applications.

Summary: This paper presents a simple method of impregnating a melamine sponge with deep eutectic solvents (DES) obtained from natural sources. The selected DES were found to have high sorption capacities, superhydrophobic and superoleophobic properties, low density, high porosity, and excellent stability. Furthermore, they can be regenerated multiple times without loss of sorption capacity. Therefore, DES-MS may serve as a green and low-cost alternative for removing oil from water.

Summary: Effective integrated methods for oil-water separation and water remediation are of great significance in the energy and environment fields. Materials with both superlyophobic and superlyophilic properties are highly desirable due to their energy-saving and high-efficiency advantages. However, the introduction of low surface tension fluorinated components may lead to environmental harm and additional contamination. Therefore, the development of materials that can achieve both oil-water separation and removal of heavy metal contamination is crucial for industrial applications and environmental sustainability.
