Abstract: An interfacial plasmonic heating intensified IP reaction (IPH-IP) is used to fabricate highly permeable and selective polyamide RO membranes. Silver nanoparticles (AgNPs) are introduced to the IP reaction interface to serve as nano-heat generators under light illumination. The coupling of generated nano-heat rapidly promotes the interfacial temperature, thereby boosting the formation of extensively “nano-foamed” polyamide with prominent nanovoids and high crosslinking degree. These features enable the resulting RO membrane to achieve a superior combination of water permeance (3.4 L m?2 h?1 bar?1) and NaCl rejection (99.7%). This outstanding separation performance further enables the membrane to efficiently remove a wide spectrum of toxic contaminants frequently found in different water sources, revealing huge potential for various water treatment applications.
