The underwater superoleophobic natural pomelo peel fibers powders coatings for efficiently oil/water separation

ABSTRACT

The natural pomelo peel fibers powders coating was obtained by spraying method, and this coating was underwater superoleophobic and could be applied in oil/water separation. The pre-wetted sample’s separation efficiency was up to 97.0% for light or heavy oils/water mixture only in gravity-driven mass flow. And the pomelo peel powders coatings could still retain more than 98.0% separation efficiency water/soybean oil mixtures after 50 separation cycles. In this article, separation efficiency of natural pomelo peel powders coated mesh was over 97.0% in different pH water/soybean oil mixtures. All these features have shown that the natural and environment-friendly pomelo peel powders coating have enough potential applications in the field of oil/water separation.

摘要

采用喷涂方法得到的天然柚子皮纤维粉末涂料，这种涂料可以应用于水下超疏油和油/水分离。的预湿样品的分离效率为97%为轻或重的油/水在重力驱动的大规模流动的混合物。和柚子皮粉涂层仍能保持98%以上的分离效率的水/大豆油混合物分离循环后50。本文研究了不同pH值水/大豆油混合物中天然柚皮粉网的分离效率达97%以上。这些特性表明，天然环保的柚皮粉涂料在油水分离领域具有广阔的应用前景。
