“…7 presents the enhanced relative permeability of each single gas measured at 25 • C and p of 50 psig as a function of T F . Matteucci et al [39,40] described that the existence of void volume (i.e., macrovoids) at the nanoparticle-polymer interface, between Fig. 7.…”

Gas transport behavior of mixed-matrix membranes composed of silica nanoparticles in a polymer of intrinsic microporosity (PIM-1) Ahn, Juhyeon; Chung, Wook-Jin; Pinnau, Ingo; Song, Jingshe; Du, Naiying; Robertson, Gilles P.; Guiver, Michael D.This article appeared in a journal published by Elsevier. The attached copy is furnished to the author for internal non-commercial research and education use, including for instruction at the authors institution and sharing with colleagues. Recently, high-free volume, glassy ladder-type polymers, referred to as polymers of intrinsic microporosity (PIM), have been developed and their reported gas transport performance exceeded the Robeson upper bound trade-off for O 2 /N 2 and CO 2 /CH 4 . The present work reports the gas transport behavior of PIM-1/silica nanocomposite membranes. The changes in free volume, as well as the presence and volume of the void cavities, were investigated by analyzing the density, thermal stability, and nano-structural morphology. The enhancement in gas permeability (e.g., He, H 2 ,O 2 ,N 2 , and CO 2 ) with increasing filler content shows that the trend is related to the true silica volume and void volume fraction. Crown

“…A separation is achieved between different permeants because of differences in the amount of material that dissolves in the membrane and the rate at which the material diffuses through the membrane. The permeability of gas A, P A , through a membrane is defined as follows (Matteucci et al, 2007;Matteucci et al, 2008):…”

“…Solubility selectivity is controlled primarily by the relative condensability of the penetrants and the relative affinity of the penetrants for the polymer matrix (Matteucci et al, 2008;Freeman and Pinnau, 1999). Both solubility and diffusivity can be influenced by particle type and concentration (Matteucci et al, 2007;Merkel et al, 2003).…”

-In relation to some inorganic membranes, polymeric membranes have relatively low separation performance. However, the processing flexibility and low cost of polymers still make them highly attractive for many industrial separation applications. Polymer-inorganic hybrid membranes constitute an emerging research field and have been recently developed to improve the separation properties of polymer membranes because they possess properties of both organic and inorganic membranes such as good hydrophilicity, selectivity, permeability, mechanical strength, and thermal and chemical stability. The structures and processing of polymer-inorganic nanocomposite hybrid membranes, as well as their use in the fields of ultrafiltration, nanofiltration, pervaporation, gas separation and separation mechanism are reviewed.

“…Unlike traditional filled-polymer composites, PNCs derive property improvements from a relatively small concentration of a well-dispersed, high-surface area discrete phase. 4 Several PNCs have been reported using various discrete phase materials, including fumed silica, [5][6][7] titanium dioxide, [8][9][10] layered mineral silicates, 2,11-13 carbon black, and graphitederived particles, such as graphite oxide, 14 thermally reduced graphite oxide, [15][16][17] and expanded graphite. 14,18 There are many potential applications for polyolefin PNCs, including automotive materials, packaging materials, electronic applications, optical applications, and applications where accelerated polymer crystallization kinetics are desired.…”

The unfavorable interaction energy between the nanoparticle and polymer-matrix provides a driving force for nanoparticle agglomeration during melt processing.…”

Herein, a new process referred to as melt-mastication (MM) is used for the first time and evaluated for dispersing nanoparticles in polymers. Compared to a conventional melt processing (CMP) technique, MM produces higher mixing torque and therefore shear in the melt during processing, resulting in the fragmentation of micrometer-scale agglomerates of exfoliated graphene nanoplatelets (xGnP) in polypropylene. The efficacy of MM compared to CMP is evaluated using quantitative stereological techniques. Stereology reveals a correlation between the steady state process torque and the spatial size distribution of agglomerates.Finally, a mechanism for agglomerate fragmentation is proposed and discussed with respect to the results.
