“…In contrast, Cloisite 30B and Cloisite BHB have a favorable impact on the methanol permeability with a more important effect in case of the better dispersed Cloisite BHB. At a 4 wt% loading of Cloisite BHB, the permeability is decreased by 51% which is almost as high as the decrease observed for completely exfoliated MMT (60%) [27][28][29][30]. Fig.…”

“…Indeed, several studies showed that addition of this type of nanofiller is able to improve the barrier properties of several polymers towards various gases, as result of a high length-to-width ratio of the additive. Upon dispersion and complete exfoliation of 1-5 wt% of layered alumino-silicates, the permeability of the polymer matrix can be decreased by 60% [27][28][29][30][31].…”

The counter-ions of montmorillonite have been exchanged for ammonium cations containing either a sulfonic acid or a carboxylic acid in order to improve the performances of sulfonated membranes in direct methanol fuel cell. These layered silicates have been dispersed within Nafion ® by solution mixing. Comparison with conventional organo-modified montmorillonite (Cloisite 30B) shows that the incorporation of carboxylic acid in the clay galleries improves the filler dispersion and, consequently, the methanol barrier properties. Moreover, the negative impact of Cloisite 30B on the ionic conductivity is restricted.

“…The organo-clay was prepared by an ion-exchange reaction between the montmorillonite silicate layers and SDS (sodium dodecyl sulfate) as the intercalating agent. The permeation rate was found to decrease, and the separation factor was found to increase upon the insertion of 2 wt.% SDS-nanoclay in the membranes [12].…”

Abstract:The design and preparation of hybrid mixed matrix membranes based on PVC (polyvinylchloride) were studied for the separation of toluene-n-heptane mixtures by pervaporation. PVC was chosen as the starting organic matrix because it is an inexpensive polymer, possessing a very high selectivity for aromatics. This property is due to the polar macromolecular structure that can induce a specific transfer of aromatic species compared with aliphatic species. To improve the performance of the PVC glassy structure, the incorporation of several inorganic micro-and nanoparticles in the polymer matrix was performed to prepare mixed matrix membranes. The results reported were obtained using several types of clay, i.e., Maghnite, Wyoming, Kaolin and Nanocor, with the goal of improving membrane permeability due to the hybrid network. Our results show that the transport properties of the modified PVC network can be drastically modified by the type and amount of particles used.

“…Therefore, there is a need for innovation in polymeric membrane technology so that the new types of membranes can successfully be used in these applications [2][3][4][5].An important recent discovery in the membrane science is the polymer nanocomposite membrane [6][7][8][9]. Here in this structurally engineered nanocomposite membranes, the nanoparticles act asto create preferential permeation pathways for selective permeation while posing a barrier for undesired permeation in order toimprove separation performance [3].…”

Mesoporous MCM-48 silica was synthesized by templating method and the structure of particles was characterized by XRD, TEM, FTIR, TGA and N 2 adsorption techniques. The surface modification of particles in order to introducing into PSF matrix was performed by DMDCS sylilation agent. PDMS surface coating of membranes was performed to repair possible surface defects and enhance selectivities of membranes. For all gases tested (N 2 , CO 2 , CH 4 andO 2 ), the permeability increased in proportion to the weight percent of MCM-48 present in the film and calculating CO 2 /CH 4 and O 2 /N 2 selectivitiesof PDMS coated membranes showed enhancement in ideal and actual selectivities both.
