Summary: In this study, a surfactant-plasticizer-synergy (SPS) assisted fabrication strategy is proposed to create a high-performance polyethyleneimine (PEI) based nanofiltration (NF) membrane. The addition of surfactant SDS and plasticizer ATBC promotes the diffusion of PEI monomer, creating a positively charged membrane surface that improves the rejection of positive ions. Additionally, the plasticizer ATBC softens the polyamide film, enhancing flexibility and water transport. Compared to the original PEI-TPC membrane, the SPS-assisted membrane shows significantly higher permeance and rejection rates for various heavy metal ions. This strategy offers a simple and cost-effective approach for the fabrication of high-performance thin-film composite (TFC) membranes.

Summary: Stretchable hydrogels have been developed to interact with biological interfaces, but lack the intelligence of biological systems. To overcome this limitation, researchers have developed asymmetric trimeric hydrogels inspired by biological ion channels. These hydrogels can sense external stimuli, encode logical responses, emulate synaptic plasticity, and even memorize images in a multistore model. Moreover, they are transparent, stretchable, and work stably under large deformation, overcoming the limitations of conventional electronic devices. This bionic design opens up possibilities for intelligent hydrogel ionotronics and bridges the gap between human-machine interfaces.
