“…Actually, GO is a kind of functional nanomaterials used widely, which contains large number of hydrophilic groups such as hydroxyl, carboxyl, and carbonyl on both sides of the sheets. Since graphene was reckoned as a strong contender to carbon nanotubes, GO-based materials have attracted a great deal of attention due to their wide applications in gas sensors [1], Li-storage [2,3], catalyst supports [4], and water purification [5]. GO nanosheets can be easily prepared by chemical exfoliation of graphite in bulk quantities.…”

Recently, 3D graphene oxide (GO) has attracted much attention due to its high specific surface area, multifunction, and facile preparation. Here, porous GO foams with extraordinary mechanical properties were prepared by using freeze-drying technique. The structure and mechanical properties of the GO foams have been characterized by X-ray diffraction, Fourier transform infrared spectroscopy, atomic force microscopy, and electronic universal testing machine. The unique structure endows the GO foams excellent elasticity, which can recover to its original shape even after compression hundreds of times. The density of GO foams has a significantly positive impact on the elastic modulus. Furthermore, the compressive strength of GO foams decreased linearly with decreasing relative humidity. A honeycomb model was constructed to investigate the effects of wall thickness, length, and included angle on the elastic modulus of GO foams. The structural evolution during the compression was revealed by finite element simulation.

“…The underwater plants are also seriously damaged. 4 Furthermore, oil-polluted water usually contains toxic chemicals, which may harm human health or even have a disastrous impact on the ecosystem. Therefore, the development of materials for the collection and removal of large amounts of organic pollutants from water is attracting global attention.…”

With the development of society, oil pollution has become more and more serious, it is becoming a global issue to separate oil and water mixture. Currently, a variety of functional materials have been successfully prepared for oil/water separation. Among them, polyurethane is an attractive candidate due to its low cost, wear-resistance and excellent mechanical properties. This report summarizes the design strategy of polyurethane-based materials and their applications in oil/ water separation. The progress made so far will guide further development of polyurethane-based materials for oil/water separation.

“…Moreover, the graphene sponge could be repeatedly used by simple treatment without obvious structure and performance degradation. Gao et al has reported three kinds of graphene oxide sponges fabricated using different freezing methods of unidirectional freezing drying, non-directional freezing drying, and air freezing drying [3]. It showed that the adsorption capacity of the graphene oxide sponges made by unidirectional freezing drying was higher than 100 g/g for all the oils tested (gasoline, diesel oil, pump oil, lubricating oil and olive oil) and had the highest value of about 122 g/g for olive oil.…”

A facile chemical route to synthesize the graphene/melamine composite sponge with super oil adsorption capacity was reported. The effect of the graphene loading on the microstructures and adsorption property of the composite sponge was studied in detail. The adsorption capacity of diesel oil in composite sponge could reach 99.0 g/g. The oil adsorbed in composite sponge could be desorption in ethanol at 50°C. Furthermore, the composite sponge exhibited excellent mechanical and environmental stability. The facile production, high stability, high adsorption capacity and recycling makes this material practically useful for the treatment of oil pollution in future.
