我们首次证明了喷墨印刷可以是一种低成本、简单、快速和可扩展的方法，用于在聚合物载体上沉积均匀（7.5-60 nm）的氧化石墨烯（GO）纳滤膜，用于高效的水净化。在改性聚丙烯腈（M-PAN）载体上成功地印刷了大面积（15 × 15 cm（2））GO纳滤膜。有机小分子的水渗透和截留率（95%）。印刷GO膜在去除药物污染物方面也表现出优异的性能，截留率接近95%，
We demonstrated for the first time that inkjet printing can be a low-cost, easy, fast, and scalable method for depositing ultrathin (7.5-60 nm) uniform graphene oxide (GO) nanofiltration membranes on polymeric supports for highly effective water purification. A large area (15 x 15 cm(2)) GO nanofiltration membrane was printed successfully on a modified polyacrylonitrile (M-PAN) support. Water permeance and rejection of small organic molecules (95%) of small organic molecules. Printed GO membranes also showed excellent performance in removing pharmaceutical contaminants, with similar to 95% rejection and
