Oily wastewater treatment has become a significant research subject due to potential environmental related applications, e.g., oil spill remedy process. In this paper, a natural polymer based hydrogel, prepared from guar gum (GG) and metaborate, was coated onto a stainless steel mesh, and the as-prepared hydrogel-coated material was applied for oil/water separation. The strong hydrophilic GG hydrogel imparted excellent underwater oleophobicity and ultra-low oil adhesion. The results proved that the as-prepared GG hydrogel-coated material possessed excellent self-cleaning property and high oil/water separation efficiency.
含油废水处理因其在环境相关应用方面的潜力，已成为一个重要的研究课题，例如，溢油补救过程。在本文中，我们制备了一种基于天然高分子的水凝胶，该水凝胶由瓜尔胶（GG）和偏硼酸钠制备而成，并将其涂覆到不锈钢网上，所制备的水凝胶涂覆材料可用于油水分离。具有强亲水性的 GG 水凝胶赋予其优异的水下疏油性和超低的油附着性。结果表明，所制备的 GG 水凝胶涂覆材料具有优异的自清洁性能和高的油水分离效率。
