Performance of Nanocomposite Membranes Containing 0D to 2D Nanofillers for CO2 Separation: A Review

Abstract

Membrane technology has the potential to be an eco-friendly and energy-saving solution for the separation of CO2 from different gaseous streams due to the lower cost and the superior manufacturing features. However, the performances of membranes made of conventional polymers are limited by the trade-off between the permeability and selectivity. Improving the membrane performance through the addition of nanofillers within the polymer matrix offers a promising strategy to achieve superior separation performance. This review aims at providing a complete overview of the recent advances in nanocomposite membranes for enhanced CO2 separation. Nanofillers of various dimensions and properties are categorized and effects of nature and morphology of the 0D to 2D nanofillers in the corresponding nanocomposite membranes of different polymeric matrixes are discussed with regard to the CO2 permeation properties. Moreover, a comprehensive summary of the performance data of various nanocomposite membranes is presented. Finally, the advantages and challenges of various nanocomposite membranes are discussed and the future research and development opportunities are proposed.

A review: the effect of the microporous support during interfacial polymerization on the morphology and performances of a thin film composite membrane for liquid purification

“…The recent advances in the microporous membrane materials revealed several interesting class of 2D llers, such as ultra-thin graphene, graphene oxide and derivate, due to their outstanding mechanical and chemical stability. 89,90 Incorporation of GO and derivate into support layer of TFC membrane could improve membrane hydrophilic and porosity, which enhanced the water permeability. Besides, functionalized support layer could affects the mechanical strength and the performance of the active layer composite membranes.…”

Polymer Nanocomposite Membranes

“…This applies both to porous and to continuous polymer composites containing nano-fillers. Great prospects in this field of membrane science are associated with the appearance of special techniques for the inclusion of nanoparticles in the material [43,52,151], with the expansion of the spectrum of nano-fillers from which a useful effect is expected [45,52,148,152,153], as well as with the appearance of methods for analyzing and visualizing the distribution and the state of fillers in matrices of different morphologies [29,51,135,154]. New polymeric materials are engaged in the synthesis of nanocomposite membranes, including those responsive to stimuli, and are also capable of self-organization or forming compositionally heterogeneous films [92,97,102,[155][156][157].…”

“…These studies raises general questions [1,30], but in most cases the analytical generalizations were made for solving specific problems of a separation [31][32][33][34][35][36] or other tasks including fuel cells or catalytic membrane reactors applications [37][38][39][40][41][42][43]. In general, it is necessary to highlight review articles in which information is collected on the introduction of a certain type of nanoparticles in polymer films of different morphologies, for example membranes-containing 0D to 2D nano-fillers [37,44,45]. Much attention was paid to the effects of introducing carbon nanoparticles into the polymer matrix [46,47].…”

Nanocomposite Membranes for Liquid and Gas Separations from the Perspective of Nanostructure Dimensions

“…Most reviews put more emphasize on the progressive advances in the development of nanocomposite membranes. The preparation and applications of nanomaterials with different dimensions have been comprehensively reviewed [ 21 , 22 , 23 ]. The potentials of 2D materials in enhancing the membrane separation performance are among the most discussed topics [ 24 , 25 , 26 , 27 , 28 , 29 ].…”
