Tóm tắt

Intelligent membranes with programmable permeance and precise sieving performance are in high demand for complex water treatment scenarios. Herein, a bioinspired membrane featuring intelligent adaptive 2D nanochannels with outstanding molecule sieving performance is reported. In particular, a protein-mimetic 2D nanochannel with pH-responsive characteristics is constructed by introducing sodium alginate (SA) molecular chains into GO laminates. The conformational transformation of SA chains under varying pH conditions enables adaptive regulation of the 2D channel size and selective molecular transport. The resulting GO-SA membrane possesses outstanding water permeance up to 122.67 L m
