大面积双尺度多孔硝化纤维素 (p-NC) 膜是通过一种简便、廉价且可扩展的穿孔方法制造的。这些p-NC膜在空气中表现出稳定的超亲水性和水下超疏油性。具有固有纳米孔和微米级穿孔阵列的p-NC膜可以选择性地、高效地从各种油/水混合物中快速分离水，效率高（> 99%）。
Large-area dual-scaled porous nitrocellulose (p-NC) membranes are fabricated by a facile, inexpensive and scalable perforating approach. These p-NC membranes show stable superhydrophilicity in air and underwater superoleophobicity. The p-NC membranes with intrinsic nanopores and array of microscale perforated pores could selectively and efficiently separate water from various oil/water mixtures with high efficiency (> 99%) rapidly.
