Spray-dispersion of ultra-small EMT zeolite crystals in thin-film composite membrane for high-permeability nanofiltration process

Thin-film composite (TFC) membranes show great potential in dye nanofiltration but their performance still required further improvement. In this work, ultra-small EMT zeolite nanocrystals were embedded into the interfacial polymerized polyamide (PA) layer supported on porous nylon via spray dispersion method and used in dye separation. Ultra-small nanosized EMT zeolite crystals with plate-like morphology were synthesized from organic-free...
