Sikorska, Wioleta; Wasyleczko, Monika; Przytulska, Malgorzata; Wojciechowski, Cezary; Rokicki, Gabriel; Chwojnowski, Andrzej published an article in 2021, the title of the article was Chemical degradation of PSF-PUR blend hollow fiber membranes-assessment of changes in properties and morphology after hydrolysis.Safety of Pentane-1,5-diol And the article contains the following content:
In this study, the authors focused on obtaining polysulfone-polyurethane (PSF-PUR) blend partly degradable hollow fiber membranes (HFMs) with different compositions while maintaining a constant PSF:PUR = 8:2 weight ratio. It was carried out through hydrolysis, and evaluation of the properties and morphol. before and after the hydrolysis process while maintaining a constant cut-off. The obtained membranes were examined for changes in ultrafiltration coefficient (UFC), retention, weight loss, morphol. assessment using SEM and MeMoExplorer Software, as well as using the Fourier-transform IR spectroscopy (FT-IR) method. The results of the study showed an increase in the UFC value after the hydrolysis process, changes in retention, mass loss, and FT-IR spectra. The evaluation in MeMoExplorer Software showed the changes in membranes’ morphol. It was confirmed that polyurethane (PUR) was partially degraded, the percentage of ester bonds has an influence on the degradation process, and PUR can be used as a pore precursor instead of superbly known polymers. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Safety of Pentane-1,5-diol
