“…Thus a highly flattened conformation in the interlayer space was formed. Similar phenomenon was also found by previous investigations (Costa and Imae, 2004;Reis et al, 2010;Decker et al, 2011;Larraza et al, 2011;Zhu et al, 2011). In the case of G5, because of hard and less flexible structure, it was difficult to be intercalated into the interlayer space due to the steric hindrance (Niu et al, 2011).…”

“…14,15 Use of hyperbranched polyesters such as those studied here in polymer/filler hybrids has recently been described in a variety of different systems demonstrating their capacity to enhance stability, increase functionality, and improve the performance of the resulting composite materials. 16 −22 On the other hand, numerous efforts are devoted on the exploitation of the properties of graphene toward the fabrication of mechanically reinforced, thermally resilient, and highly conductive composites. 23−29 Therefore, it is expected that combination of the advantageous features of these two components may result in high-end materials with superb physical properties while keeping the cost low.…”

We explore by means of molecular dynamics (MD) simulations mixtures of graphene with hyperbranched polyesters (Boltorn) of two different pseudogenerations in a wide range of temperatures. Static and dynamic features of the polymeric component are probed in order to assess the effects of the presence of graphene in the polymer's behavior, while we also examine the structural rearrangement of the graphene sheets in the presence of a noncrystallizable highly branched polymeric component. Our results show that graphene platelets are forming stacks comprised by a small number of flakes (typically 2−3) which are dispersed within the polymeric matrix. The characteristics of the spatial arrangement of the graphene planes and that of the formed clusters (including their relative orientation) depend sensitively on the temperature and on the size of the hyperbranched component. From the dynamic point of view, a significant slowing down is detected both in local and in global polymer dynamics in composite systems. The strong dynamic slowing down is accompanied by the occurrence of a glass-like transition at a considerably higher temperature compared to that characterizing the respective pristine polymer systems. We believe that the results reported in the present study capture also generic characteristics of the behavior of such materials and therefore could be exploited for a better control of the mechanical and thermal characteristics of hyperbranched polymer/graphene systems in a more general aspect.

“…The final properties of the nanocomposites are largely influenced by the clay's aspect ratio, dispersion and alignment as well as the polymer-polymer and polymerclay interface interaction. There are three methods most commonly used in the fabrication of nanocomposites namely in situ intercalative polymerization, intercalation of melt and intercalation polymer from solution [11][12][13]. In situ polymerization requires the use of monomer to swell the silicate layers and upon subsequent polymerization, the intercalated sheets are filled with polymer chains.…”

Application of polymer clay nanocomposites for carbon dioxide (CO2) removal in gas separation by using mixed matrix membranes is promising due to the advancement of nanotechnology and polymer processing. In this regard, as clay is abundantly available, cheaper and has attractive physical and chemical properties, the incorporation of these silicate layers within the polymer matrix as filler is favourable. In principle, the exfoliated clay single layers create higher tortuosity effects and may improve the separation properties of the membrane. This review presents a synopsis of the polymer clay nanocomposites development and applications as well as their potential for the removal of CO2 from gas mixtures. Details of the recent works in the development of mixed matrix membranes embedded with clay for gas separation were also discussed. In addition, the problems and mechanism to evaluate the exfoliation properties were emphasized identifying the gaps and motivates for future research works utilizing clay nanoparticles as membrane filler.
