  • NANOPARTICLE-ONLY LAYER BY LAYER SURFACE MODIFICATION OF SUBSTRATE MEMBRANE
    Publication number: 20140141176
    Abstract: Method and system for fabricating a thin film composite including providing a porous polymeric substrate membrane having a surface. At least one polyelectrolyte later can be deposited onto the surface of the substrate membrane, which can impart a charge to the surface. The substrate membrane can be immersed into a bath including a nanoparticle solution, thereby depositing at least one nanoparticle-only layer on the substrate membrane to form a thin film composite.
