  Abstract

Nylon mesh has been applied in various fields because of its intrinsic mechanical and chemical stability. However, its application is limited by its surface property. In this work, nylon mesh was first designed to integrate with a zeolitic imidazolate framework-67 (ZIF-67) with a distinct hydrophobic property. Herein, the mechanically stable nylon mesh/ carboxymethyl chitosan/ZIF-67 (NY/CMCS/ZIF-67) composite membranes were prepared via layer-by-layer self-assembly of CMCS surface functional groups to coordinate with cobalt ion and in situ growth of ZIF-67. The prepared NY/CMCS/ZIF-67 membranes were characterized by Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and thermogravimetric analysis. After modifications, the ZIF-67 content in the membranes reached 22 %. The water contact angle increased from 47.5
