Synthesis and Characterization of Multifunctional Metal‐Organic Framework (Ni‐ZIF‐67) Decorated Waterborne Polyurethane (Ni‐ZIF‐67/WPU) Nanocomposites: Sonochemical Approach

Abstract This work investigates the effect of a modified nickel‐doped metal‐organic framework (Ni‐ZIF‐67) as filler on thermal, mechanical, and water vapor permeability properties environmentally friendly waterborne polyurethane (WPU). The facile greener ultrasound (sonochemical) technique is developed to prepare multifunctional Ni‐ZIF‐67@WPU nanocomposites, exhibiting superior crystallinity uniform distribution. resultant Ni‐ZIF‐67 nanoparticles films are characterized by various techniques, including powder XRD, FE‐SEM, FTIR, TGA, UTM, contact angle, antibacterial properties. nanocomposites exhibited excellent three‐fold mechanical performance (tensile strength ≈22 MPa) at very low 5 wt.% loading high thermal stability compared pristine WPU. In addition, optimum 5.0 with potential application. Demonstrate that rapid synthesis approach can enhance interaction matrix, surface area, tuneable pore size material. new insight has green for fabricating advanced toward practical utilization.
