Web1 day ago · The attachment of ZIF-67 crystals was slightly reduced, possibly due to the exfoliation of a few ZIF-67 while grafting LA by immersion stirring method. Compared with the well-defined dodecahedral crystal structure of ZIF-67 in MGZ, the surface of ZIF-67 in LA/MGZ was covered with a rough pleated structure, and partial crystals formed defects.
