摘要:近年来，因为各种运输的油船漏油导致水体污染事故时有发生，海洋生态环境受到了极大的破坏。研究发现，对海洋中生物影响最大的是其中的溶解油，水中的生物与溶解油接触会生成威胁巨大的毒素。由于海水成分及海体环境复杂多变，溶解油的含量又很少，因此目前对于海中溶解油的处理方法没有完善的研究。在此基础上，本论文研究了石墨烯材料对水中溶解油的吸附行为来探讨石墨烯吸油材料的可行性。本文采用氧化还原的方法制备石墨烯，以P123作为模板制备石墨烯气凝胶，并通过SEM、TGA、Raman、红外等表征手段对材料的表面形貌、微观结构、亲油性、疏水性等进行分析。78831

Preparation and Oil Absorption of Polymeric Template Modified Graphite Gel 

Abstract : In recent years, due to a variety of transport oil tanker oil pollution caused by water pollution accidents have occurred, the marine ecological environment has been greatly damaged。 The study found that the greatest impact on the biological life of the ocean is one of the dissolved oil, water biological and dissolved oil contact will generate a huge threat to toxins。 As the seawater composition and the marine environment is complex and varied, the content of dissolved oil is very small, so there is no perfect study on the treatment method of dissolved oil in the sea。 On the basis of this, the feasibility of the graphene oil on the adsorption behavior of the dissolved oil in water was studied in this paper。 In this paper, graphene was prepared by oxidation-reduction method, and graphene aerogels were prepared by using P123 as template。 The surface morphology, microstructure, lipophilicity and hydrophobicity of the materials were studied by SEM, TGA, Raman and infrared analysis。
