In the present study; halloysite nanotubes (HNTs) were firstly functionalized using N-β-(aminoethyl)-γ-aminopropyltrimethoxy silane and then employed as nanofillers to fabricate mixed-matrix membranes including poly (ether-block-amide) polymer as the primary material. To characterize the HNTs; as well as the obtained membranes; thermal gravimetric analysis; Fourier-transform infrared spectroscopy; X-ray powder diffraction; and Field emission scanning electron microscopy analyses were employed. Effects of the modified and pure HNTs loadings; as well as feed pressure on CH4 and CO2 permeabilities and ideal CO2/CH4 selectivity of the prepared membranes; were surveyed. The experimental permeation results indicated that incorporation of 1.5 wt% of amine-functionalized HNTs into the polymer matrix improves CO2 permeability and the ideal selectivity by nearly 37 and 24%; respectively; due to the higher CO2 adsorption capacity of the amine-functionalized HNTs. © 2021 Wiley Periodicals LLC;
