Fig. 3: Membrane morphologies altered by the interfacial polymerization process.
From: Microporous organic nanotube assisted design of high performance nanofiltration membranes
Control TFC membrane: a surface SEM and d AFM images (inset: root‒mean‒square roughness, Rq). N-TFN membrane: b surface SEM image, c cross-sectional SEM image, e AFM image (inset: root‒mean‒square roughness, Rq), and f AFM image and height profile (insert) of freestanding N-TFN membranes. The N-TFN membranes shown were prepared using a NT-OEt loading of 2.6 μg cm−2. MD simulations of diamine molecules diffusion in water and in the nanotube-water system: g simulation box including the PIP monomers in water only, h simulation box including the PIP monomers in water with the NT-OEt nanotubes, i the MSD curves for the PIP molecules in the two simulation box systems, with the slope of the linear regression line used to calculate PIP diffusivities.
