Abstract

With the serious water contamination by frequent oil spill accidents and industrial wastewater emissions, superhydrophobic materials for oil–water separation have attracted considerable attention. In this study, an easily-prepared superhydrophobic paper was provided by using the dip-coating method, which involved depositing dopamine, copper sulfate, and dodecanethiol layer by layer on the surface of the paper to form a dense superhydrophobic surface. The prepared modified paper surface possessed excellent superhydrophobicity with a water contact angle (WCA) of 162° and an oil–water separation efficiency of more than 99% could be reached. Even after 40 cycles of oil–water separation, the separation efficiency and the water contact angle were still kept more than 95% and 150°, respectively. Additionally, the prepared superhydrophobic paper exhibited good self-cleaning properties and was highly resistant to acid, alkali, salt, and organic solutions. As a result, this study provided a new simple method to prepare functional superhydrophobic materials for oil–water separation.

期刊介绍： Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
