  • development of nanocomposite membranes containing modified si nanoparticles in pebax 2533 as a block copolymer and 6fda durene diamine as a glassy polymer
    ACS Applied Materials & Interfaces, 2014
    Co-Authors: Vajiheh Nafisi, May-britt Hägg
    Abstract:

    Nanocomposite membranes of modified Si nanoparticles as Inorganic Filler in two different polymers from two different categories were developed. Synthesized 6FDA-durene diamine as a glassy polymer and PEBAX-2533 as a block copolymer were used as the polymer matrix to develop the nanocomposite membranes of modified Si nanoparticles in polymer matrix. The scanning transmission electron microscopy (STEM) results showed nice nano size dispersion of Inorganic nanoFillers in the polymer matrix in both cases. Pure gas permeation for the gases CO2, CH4, N2, and O2 and mixed gas of CO2–N2 was carried out at 2 and 6 bar for single gas and 2.6 bar for mixed gas using the developed nanocomposite membranes. The loading of Inorganic Fillers in the PEBAX-2533 polymer matrix resulted in a dramatic increase in gas permeability for all tested gases, while a decrease was observed for CO2/N2 and CO2/CH4 selectivities with small amounts of loading of Filler. With higher loading of Inorganic Filler, the selectivity did not cha...

  • development of dual layer of zif 8 pebax 2533 mixed matrix membrane for co2 capture
    Journal of Membrane Science, 2014
    Co-Authors: Vajiheh Nafisi, May-britt Hägg
    Abstract:

    Abstract A new kind of self-supported dual layer mixed matrix membrane was developed in this work using ZIF-8 as Inorganic Filler in PEBAX-2533 polymer matrix. The developed dual layer flat sheet mixed matrix membrane was characterized to investigate the morphology of organic-based and Inorganic-based layer. The gas separation properties of the mixed matrix membranes were tested using single gases CO2, CH4, N2, and O2 and a mixture of CO2 and N2 in dry and humidified conditions. The permeability of all examined gases increased as the Inorganic Filler content increased in the matrix membranes, and specifically it increased dramatically for CO2 in all cases, single feed gas and dry and humidified mixed gas. The CO2/N2 selectivity decreased slightly from 33.8 for the pure PEBAX membrane to 32.3 for the mixed matrix membrane with 35% ZIF-8 loading, while more significant drop in CO2/N2 selectivity was observed in experiments using mixed gases.

  • gas separation properties of zif 8 6fda durene diamine mixed matrix membrane
    Separation and Purification Technology, 2014
    Co-Authors: Vajiheh Nafisi, May-britt Hägg
    Abstract:

    Abstract Mixed matrix membranes of ZIF-8 as Inorganic Filler in polymer matrix of synthesized 6FDA-durene diamine was developed in this work. Pure gas permeation for the gases CO 2 , CH 4 , N 2 , and O 2 and mixed gas of CO 2 /N 2 was carried out at 2 and 6 bar for single gas and 2.6 bar for mixed gas using the mixed matrix membrane of ZIF-8/6FDA-durene diamine in different Inorganic Filler loading. The homogenous dispersion of ZIF-8 particles in polymer confirmed by SEM result in dramatic increase in gas permeability for all tested gases and significant increase in CO 2 permeability from 1468 Barrer to 2185 Barrer corresponding to pure polymer membrane and 30 wt% loaded ZIF-8 mixed matrix membrane at 2 bar feed gas pressure, respectively. However a loss in both CO 2 /N 2 and CO 2 /CH 4 selectivity was observed. Incorporation of Inorganic Fillers in membrane results in increment of decomposition temperature of mixed matrix membranes while no significant change in T g was observed.

  • new approaches towards novel composite and multilayer membranes for intermediate temperature polymer electrolyte fuel cells and direct methanol fuel cells
    Journal of Power Sources, 2016
    Co-Authors: Carolina Musse Branco, Surbhi Sharma, Maria Madalena De Camargo Forte, Robert Steinbergerwilckens
    Abstract:

    Abstract This review analyses the current and existing literature on novel composite and multilayer membranes for Polymer Electrolyte Fuel Cell applications, including intermediate temperature polymer electrolyte fuel cell (IT-PEFC) and direct methanol fuel cell (DMFC) systems. It provides a concise scrutiny of the vast body of literature available on organic and Inorganic Filler based polymer membranes and links it to the new emerging trend towards novel combinations of multilayered polymer membranes for applications in DMFC and IT-PEFC. The paper carefully explores the advantages and disadvantages of the most common preparation techniques reported for multilayered membranes such as hot-pressing, casting and dip-coating and also summarises various other fresh and unique techniques employed for multilayer membrane preparation.
