“…Most commonly, PIs are widely used in gas separation applications due to their high thermal stability and enhanced mechanical properties (Kapantaidakis et al, 1999). However, polyimide has the problem of plasticization by CO 2 in gas filtration applications, and adding GO to the polymer matrix can improve/solve these material problems (Kapantaidakis and Koops, 2002).…”

This paper expresses a short review of research on the effects of graphene oxide (GO) as a nanocomposite element on polymer morphology and resulting property modifications including mechanical, barrier, and electrical conductivity. The effects on mechanical enhancement related to stress measurements in particular are a focus of this review. To first order, varying levels of aggregation of GO in different polymer matrices as a result of their weak inter-particle attractive interactions mainly affect the nanocomposite mechanical properties. The near surface dispersion of GO in polymer/GO nanocomposites can be investigated by studying the surface morphology of these nanocomposites using scanning probe microscopy such as atomic force microscope (AFM) and scanning electron microscope (SEM). In the bulk, GO dispersion can be studied by wide-angle X-ray scattering (WAXD) by analyzing the diffraction peaks corresponding to the undispersed GO fraction in the polymer matrix. In terms of an application, we review how the hydrophilicity of graphene oxide and its hydrogen bonding potential can enhance water flux of these nanocomposite materials in membrane applications. Likewise, the electrical conductivity of polymer films and bulk polymers can be advantageously enhanced via the percolative dispersion of GO nanoparticles, but this typically requires some additional chemical treatment of the GO nanoparticles to transform it to reduced GO. ª 2015 Production and hosting by Elsevier B.V. on behalf of King Saud University.

“…However, at magnification of 1200 the optical microscopy of the cured films showed phase separation [14]. This was attributed to heating the cast film above the glass transition temperature of PSF before and during polymerization of BMI that led to a phase separation as illustrated elsewhere [12,15]. However, an improvement in the synthesis of semi-IPN was achieved in the work of Liou et al [16] when BMI oligomer/polyimide was mixed in a rotary roller for 24 h within a highly viscous NMP/polyimide solution.…”

“…The first type of membrane material is glassy polymer which consists of stiff chain and lower free volume that stringently separates based on size of the components and it favors small molecule to pass through the membrane. While, the second type of membrane is highly flexible, rubbery and has high free volume that separates the component based on condensability where it prefers to separate larger components [13].…”

Abstract-A new bang of natural gas demand has opened up the opportunities towards the utilization of membrane technology for the purification process.The advantages in terms of smaller footprint, lower weight, minimum utility requirement and low labor intensity make them appropriate for wide scale applications. Polymeric membrane is one of the greatest emerging fields in membrane material development. Nevertheless, the separation performance of the existing polymeric materials were reached a limit in the trade-off between permeability and selectivity. The development of inorganic material gives a significance improvement in membrane performance but it outrageously expensive for many applications and having complicated procedure during fabrication process have limit the application of inorganic membrane in gas separation. Thus, a rapid demand in membrane technology for gas separation and the effort toward seeking the membranes with higher permeability and selectivity has motivated the development of mixed matrix membrane. Mixed matrix membrane (MMM) which incorporating inorganic fillers in a polymer matrix is expected to overcome the limitations of the polymeric and inorganic membranes. Apart from an overview of the different membrane materials for gas separation, this paper also highlights the development of mixed matrix membrane and challenges in fabrication of mixed matrix membranes.
