Název v původním jazyce

A study on the relationship between preparation condition and properties/performance of polyamide TFC membrane by IR, DSC, TGA, and SEM techniques

Popis výsledku v původním jazyce

High-performance thin-film composite polyamide membranes for inorganic solute separation were prepared by the polymerization of trimesoyl chloride (TMC) with diethylenetriamine, 1,3-cyclohexanebis(methylamine), 2,3-diaminopyridine (DAP), m-phenylenediamine (MPD), piperazine (PIP) or a mixture of MPD and PIP/DAP, on the surface of polyethersulfone (PES) membrane support. The characteristics of the skin layers were studied by IR spectroscopy, DSC, TG analysis, and SEM techniques. It was attempted to correlate the observed flux and rejection properties of the membranes with their preparation conditions such as reactant concentrations, reaction time, etc. The TGA thermograms show that the initial decomposition temperatures of the PES and polyamide blends are in the range of 330?400°C, which is about 20?90°C lower than that of PES (420°C). SEM images display that the top polyamide skin surface presents a honeycomb-like structure and the cross-section image of the membranes clearly displays
