文摘

Heat curing of polyamide membrane in steam and water media was devised. The ability of humidity-controlled medium for PA chemical modification was evidenced. Steam-cured membrane revealed great surface hydrophilicity, flux, and rejection. Water-cured membrane revealed extra high surface hydrophilicity and rejection.
