“…Aluminum foil and A4 sized paper were also tested to give better comparison of mechanical properties. Aluminum foil from Reynolds Wrap ® has the thickness of 20 μm and weight per unit area of 0.00454 g/cm 2 while printing paper of size A4 from Paperone ® has the thickness of 110 μm and weight per unit area of 0.008 g/cm2. Tensile tests of sheets with different stretching ratios were performed.…”

Oil spill on water surface and shorelines has been a major source of water pollution. With the damaging impact to ecology and the long term effects of environmental pollution, demand for materials for cleaning up the water in a quick and effective way has increased. A number of sorbents have been recommended for the purpose of picking up oil from water. These range from natural products, such as inorganic porous products and organic biodegradable products. However, most of them reveal limited oil sorption capacity and also absorb water. Hence, it is felt that there is a need of producing a synthetic oil sorbent that not only has high sorption capacity but also, unlike other contemporary synthetic sorbents, proves to be strong and cost effective. In this paper, we are presenting a novel super oil sorbent polymer (oil-sap) sheet consisting of ultrahigh molecular weight polyethylene (UHMWPE). The sorbent exhibits an uptake capacity of (276 g/g) and pickup density of (58 g/cm 3 ). In addition, it comprises a mechanically strong structure (tensile modulus and breaking stress of 1332 MPa and 171 MPa respectively). The unique blend of uptake capacity and strength along with cost effectiveness of the raw material (polyethylene) makes these sheets feasible candidates for mass production and application.

“…Therefore, developing a reasonable method of fast and high efficiency to remove oil pollutants from water surface is increasingly imperative and necessary. Up to date, various strategies such as mechanical extractions , chemical dispersants , bioremediation , in situ combustion , chemical degradation , and activated carbon have been considered to clean spilled oil and wasteful oil of life from aqueous wastewater. In contrast, the most economical and efficient method to deal with oil spills should be granted to absorption by the petroleum‐based polymers oil‐absorbents owing to its flexibility, simplicity of design, ease of operation, and insensitivity to toxic pollutants.…”

NSM‐g‐P(MMA‐co‐BA) resin with super oil‐absorbent capability was prepared by grafting co‐polymerization using Nitraria seeds meal as filler, methyl‐meth‐acrylate (MMA) and butyl‐acrylate (BA) as monomers, N,N′‐methylene‐bis‐acrylamide (MBA) as crosslinker and peroxide‐benzoyl (BPO) as initiator. The structure of obtained products was analyzed using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM), respectively. The oil absorbency, reusability, oil‐retention capacity, thermodynamics, and the removal of oil from the surface of 0.9 wt% NaCl solutions were examined further. The results showed that NSM‐g‐P(MMA‐co‐BA) can absorb lubrication up to 29.6 times of its weight, 24.3 times for colza oil, 22.7 times for diesel, and 21 times for gasoline. The exhausted NSM‐g‐P(MMA‐co‐BA) can be recollected and recovered through extraction or drying approach. More importantly, the oil sorption capacity of recovered NSM‐g‐P(MMA‐co‐BA) only has a slight decline after six sorption cycles. The thermodynamic studies indicated that adsorption procedure with complex physical and chemical sorption is spontaneous and exothermic. In general, the present composite resins have exhibited potential applications in cleanup of oil spills because of their good hydrophobicity, lipophilicity, and excellent network structure. Also, the findings of this study might provide a convenient and economic method for fast and selective removal of oil from surface of wastewater. POLYM.

“…One such combative measure is the use of sorbent materials in order to uptake the spilt liquid. Sorbents have so far been made on the basis of a variety of materials including natural organic biodegradable products such as straw, hull, corncob, peat moss, sugar cane bagasse, wood/cotton fibers, wool‐based stuff, and silkworm cocoon waste and multifarious inorganic porous products (e.g., talc, clay, zeolites, silica, aerogel, and calcium fly ash) . However, most sorbents have limitations such as limited oil sorption capacity and also high sorption of water .…”

This paper presents the oil uptake of porous sorbent polymer sheets consisting of ultra‐high molecular weight polyethylene. A comprehensive set of experiments are performed showing the saturation contact time, retention value, mechanical properties, oil pick‐up ratio, pick‐up density, and dynamic dripping profile. Kinetic modeling of the oil sorption is also provided. The experimental results show a good correlation with the pseudo‐second order model. The sheets exhibit high oil uptake speeds, requiring less than 2 min in contact with the oil to reach saturation. The sheets fulfill the criteria of high uptake kinetics, high sorption capacity, and high mechanical strength simultaneously. Those characteristics enable their use in practical spill response.
