Gradients played a pivotal role in membrane technologies, e.g., osmotic energy conversion, desalination, biomimetic actuation, selective separation and more. In these applications, the compositional gradients are of great relevance for successful function implementation, ranging from solvent separation to smart devices. However, the construction of functional gradient in membranes is still challenging both in scale and directions. Inspired by the specific function-related, graded porous structures in glomerular filtration membranes, we report here a general approach for constructing gradient covalent organic framework membranes (GCOMx) applying poly (ionic liquid)s as template...
