摘要: Abstract MXenes as an emerging class of 2D metallic carbide/carbonitrides materials have great potentials in designing and fabricating functional polymer composites. In this study, Ti 3 C 2 T x a representative MXene was employed to fabricate thin-film nanocomposite (TFN) membranes. The abundant surface groups (mainly OH) on allowed facile modification, thus evenly functionalized nanosheets were obtained. Four grafted respectively, which found strongly affect the affinity towards solvent molecules further determine transport properties Interestingly, , namely NH COOR, 6 H 12 26 could effectively enhance flux for isopropanol, ethyl acetate, toluene, n -heptane, no matter matrix hydrophilic or hydrophobic. This finding indicated that task-specific function be distinctly transferred TFN Moreover, blocked permeation solute molecules, resulting high rejection ability.
