a Photographs showing the wettability of DPA, DPAS, and DPAS@P-GOM (left) and the corresponding water contact angle (right). b Water contact angle (WCA) cyclicity of various hydrogels. SEM images of DPAS hydrogel, c, e unmodified and d, f modified by GO immersing in water, and the corresponding enlarged images. g Transport pathways of the water molecules, organics, and metal ions in the DPAS hydrogel coated by P-GO functional membranes (DPAS@P-GOM).
