The FTIR spectra of the prepared Pebax ® 2533-UiO-66-NH 2 /PP thin film mixed matrix hollow fiber membranes are similar to the FTIR spectra of pristine Pebax ® 2533/PP hollow fiber...

The bionanocomposite nanostructures were characterized by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimeter (DSC) while their rheological properties and thermal ...

2021年8月1日 · FTIR-ATR spectra of membranes prepared by phase inversion with the 0.5 wt% casting solution concentration and a different number of layers (from 3 to 6) compared to that of the bare PSF support and the Pebax® 3533 dense membrane.

Unstabilized poly (ether block amide) (PEBA, PEBAX) of the type used in angioplasty balloons was aged at temperatures of 18–85°C for periods of up to 313 days. Since PEBA is used in safety...

2019年7月15日 · FTIR and Raman spectroscopy were utilized to verify that the Pebax-MoS2 membranes were well prepared. The gas permeability results showed that the Pebax membrane doped with 4.76 wt % MoS2 nanosheets had the best performance, with a CO 2 permeability of 67.05 Barrer and CO 2 /N 2 selectivity of 90.61.

2014年6月1日 · PEBAX block copolymers, which are synthesized from dicarboxylic acid terminated aliphatic polyamides and polyoxyalkene glycols, have been investigated for gas separation properties and have shown a nice potential for CO 2 separation [35].

2019年3月12日 · In this study, PEBAX-1657 was utilized to increase the permeance. Poly (ether-block-amide) resin is known as the trademark PEBAX, which is a thermoplastic elastomer consisting of linear chains....

FTIR results at various time points after PEBAX reflow show gradual reincorporation of the polyether oligomer (polyether signal decreases over time). A corresponding increase in the amide signal from the underlying block amide component was also observed.

2019年8月7日 · In this study, to increase the selectivity, PEBAX-5513, which increased the ratio of the amide groups capable of showing high selectivity, was selected as the polymer matrix. SEM images were...

The performance of CO2/CH4 separation of (Pebax) mixed matrix composite hollow fiber membranes, incorporated with ZeY and aminosilane-modified zeolite Y (Mo-ZeY), is investigated.
