Fabrication of nanocomposite membrane based on post-synthetic modification of two-dimensional metal-organic framework nanosheet

• Post-synthetic modification of two-dimensional metal-organic framework. CuBDC-NH 2 nanosheet reacts with isocyanate-terminated polyurethane oligomer(PU). The /PU is conducted to prepare functional nanocomposite membrane. membrane shows over 93.0% removal rate for dye removal. Two-dimensional framework (2D MOF) becoming as an attractive type 2D materials. And (PSM) provides a powerful method modify the structure MOF without altering its crystal topology, which can generate MOFs not accessible from direct synthesis and improve compatibility between other components in MOF-based composite materials, especially MOF/polymer composite. In this work, facile based on PSM polymers First, amino-functioned nanosheet, (BDC-NH 2-amino-1,4-benzenedicarboxylate), has been prepared precursor. Then (PU) oligomer through obtain membrane, show removal, such methylene blue, Rhodamine B Eosin Y.
