Report on optimizations and control of porosity and surface chemistry in graphene-based membrane

The porous materials will be infiltrated with low cost IEM eg SPEEK SPES dissolved in a suitable solvent in order to get a compenetrated multilayer reducing the impedance associated to the thick membrane commonly used in membraneassisted processes maximizing the interface and allowing to higher energy conversion efficiency Additional infiltration can be obtained by ALD process in order to have atomiclayer thick metaloxides inside the GO channel Moreover interlayer distance will be controlled and partially tuned by acting on the drying state and exploiting functional link acting as spacers Other 2D materials such as MXenes will be considered for the fabrication of composite membranes
