Abstract Polymeric nanocomposite membranes are emerging types of membranes that have the potential to improve the current state of gas separation technologies. The incorporation of inorganic nanofillers into polymeric membranes provides an interesting approach to modify their gas permeability and separation properties and enhance their efficiencies. In this research, the PhD candidate pursued the development of several nanocomposite membranes, with the focus on inorganic nanofillers, for gas separation and removal applications. The gas species of interest in this work were hydrogen (H2), methane (CH4) and hydrogen sulphide (H2S). At the initial stage, the author of this thesis thoroughly reviewed the properties, gas transport mechanism, and synthesis methods of polymeric membranes with inorganic nanofillers. As a result, informed choices were made regarding the incorporation of carbon black (CB), multi walled carbon nanotubes (MWCNT) and silver (Ag) nanoparticles in polydimethylsiloxane (PDMS) polymeric matrix. Nanocomposite membranes containing variable weight amounts of these nanofillers were fabricated to evaluate their effect on gas separation properties. In summary, the author believes that the developed membranes demonstrated the ability to efficiently separate and remove various gas species including H2, CH4 and H2S. These developed nanocomposite membranes are also efficient and low cost solutions for separating other gas species which offer a plethora of applications for environmental, agricultural, biotechnology and energy conversion systems. This work added significantly to the fundamental understandings in the field of nanocomposite membranes for gas separation and removal.
