Surface-tailoring chlorine resistant materials and strategies for polyamide thin film composite reverse

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 5,   Pages 564-591 doi: 10.1007/s11705-021-2109-z

Abstract: Polyamide thin film composite membranes have dominated current reverse osmosis market on account of theirpromising separation performance, chlorine-induced degradation resulted from the susceptibility of polyamidetoward chlorine attack has been regarded as the Achilles’s heel of polyamide thin film composite.chlorine treatment can impair membrane performance through chlorination and depolymerization of the polyamideThe advancement in the development of chlorine resistant polyamide thin film composite membranes is reviewed

glycol on the crystallization, rheology and foamability of poly(lactic acid) containing generated polyamide

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 12,   Pages 2074-2087 doi: 10.1007/s11705-023-2342-8

Abstract: this study, the rheological properties, crystallization and foaming behavior of poly(lactic acid) with polyamidePolyamide 6 particles were deformed into nanofibrils during drawing.For the 10% polyamide 6 case, polyethylene glycol addition reduced the polyamide 6 fibril diameter from365.53 to 254.63 nm, owing to the smaller polyamide 6 particle size and enhanced interface adhesion.The presence of higher aspect ratio polyamide 6 nanofibrils substantially enhanced the melt strength
