General schematic representation of solution blending method of NM incorporation in IEMs. The polymer is dissolved in a solvent, followed by addition of the NMs. Hereafter, the solution is thoroughly mixed (usually via sonication or stirring) to ensure a uniform dispersion of the NM in the polymer. Afterwards, the solvent is removed (by phase inversion) and the NMs are rearranged and embedded in the polymer to form mixed matrix membranes
