The AC particles had a mean particle size of 1.5 \u03bcm and a mean pore diameter of 1.9 nm. The films were prepared by slow solvent evaporation from casting solutions in chloroform, which had a varying polymer\u2013AC ratio. It was possible to produce stable films with up to a content of 50 vol % of AC. Thorough characterization experiments were accomplished via differential scanning calorimetry and thermogravimetric analysis, while the morphology of the MMMs was also investigated via scanning electron microscopy. The gas transport properties were revealed by employing time-lag measurements for different pure gases as well as sorption balance experiments for the filler particles. It was found that defect free Matrimid\u00ae MMMs with AC were prepared and the increase of the filler content led to a higher effective permeability for different gases. The single gas selectivity \u03b1ij of different gas pairs maintained stable values with the increase of AC content, regardless of the steep increase in the effective permeability of the pure gases. Estimation of the solubilities and the diffusivities of the Matrimid\u00ae, AC, and MMMs allowed for the explanation of the increasing permeabilities of the MMMs, with the increase of AC content by modelling.<\/jats:p>","DOI":"10.3390\/polym10010051","type":"journal-article","created":{"date-parts":[[2018,1,8]],"date-time":"2018-01-08T12:26:02Z","timestamp":1515414362000},"page":"51","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":66,"title":["Development and Characterization of Defect-Free Matrimid\u00ae Mixed-Matrix Membranes Containing Activated Carbon Particles for Gas Separation"],"prefix":"10.3390","volume":"10","author":[{"given":"Fynn","family":"Weigelt","sequence":"first","affiliation":[{"name":"Helmholtz-Zentrum Geesthacht, Institute of Polymer Research, Max-Planck-Stra\u00dfe 1, 21502 Geesthacht, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6394-0628","authenticated-orcid":false,"given":"Prokopios","family":"Georgopanos","sequence":"additional","affiliation":[{"name":"Helmholtz-Zentrum Geesthacht, Institute of Polymer Research, Max-Planck-Stra\u00dfe 1, 21502 Geesthacht, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8757-600X","authenticated-orcid":false,"given":"Sergey","family":"Shishatskiy","sequence":"additional","affiliation":[{"name":"Helmholtz-Zentrum Geesthacht, Institute of Polymer Research, Max-Planck-Stra\u00dfe 1, 21502 Geesthacht, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Volkan","family":"Filiz","sequence":"additional","affiliation":[{"name":"Helmholtz-Zentrum Geesthacht, Institute of Polymer Research, Max-Planck-Stra\u00dfe 1, 21502 Geesthacht, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Torsten","family":"Brinkmann","sequence":"additional","affiliation":[{"name":"Helmholtz-Zentrum Geesthacht, Institute of Polymer Research, Max-Planck-Stra\u00dfe 1, 21502 Geesthacht, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4840-6611","authenticated-orcid":false,"given":"Volker","family":"Abetz","sequence":"additional","affiliation":[{"name":"Helmholtz-Zentrum Geesthacht, Institute of Polymer Research, Max-Planck-Stra\u00dfe 1, 21502 Geesthacht, Germany"},{"name":"Institute of Physical Chemistry, University of Hamburg, Martin-Luther-King-Platz 6, 20146 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,1,8]]},"reference":[{"key":"ref_1","unstructured":"Baker, R.W.
