A poly(amidoamine) nanoparticle cross-linked two-dimensional metal-organic framework nanosheet membrane for water purification.

Amphiphilic metal-organic framework nanosheet membranes with poly(amidoamine) (PAMAM) nanoparticles to serve as nanosheet cross-linkers are fabricated via vacuum filtration. The PAMAM cross-linked nanosheet membrane shows an outstanding structural stability in water solution and displays a remarkably enhanced rejection rate for dye molecules.
