Abstract It’s still a big challenge to access a suitable natural derived film with superb flexibility and stable structure for oil/water separation. Herein, we described a facile method to prepare a natural flexible film derived from cajeput bark (CB). The film exhibits superhydrophobic and superoleophilic; the oil adsorption and oil/water separation results showed the film possesses a relative high adsorption capacity and extremely high flux (∼2700 L m−2 h−1) for oil/water separation. Hence, the film, with low-cost, environmental friendly character, accessibility and superb flexibility, might be a promising candidate for the cleanup of oil spill and oil/water separation.

来自cajeput树皮的天然柔性超疏水膜用于油/水分离

摘要 获得合适的具有优异柔韧性和稳定结构的天然衍生薄膜用于油水分离仍然是一个很大的挑战。在这里，我们描述了一种简便的方法来制备源自 cajeput 树皮 (CB) 的天然柔性薄膜。薄膜表现出超疏水和超亲油性；油吸附和油水分离结果表明该薄膜具有较高的吸附能力和极高的油水分离通量（~2700 L m-2 h-1）。因此，该薄膜具有低成本、环保特性、可访问性和极好的柔韧性，可能是清理溢油和油/水分离的有前途的候选者。
