Dismantlable adhesive using coordination polymer/metal organic framework
We explored the use of meltable metal-organic frameworks and coordination polymers (MOFs/CPs) as dismantlable adhesives that can be readily disassembled by immersion in water at room temperature. Three MOF/CP materials were synthesized, melted, and applied to copper substrates to evaluate their shear bonding strength. Among these, [Zn(HPO<sub>4</sub>)(H<sub>2</sub>PO<sub>4</sub>)<sub>2</sub>](H<sub>2</sub>Im)<sub>2</sub> (ZPI) exhibited the highest shear strength (~ 10 MPa), indicating its suitability as a high-strength adhesive. Moreover, ZPI-bonded joints showed a marked decrease in bond strength after just one hour of immersion in water at room temperature, allowing for manual disassembly. These findings highlight the potential of ZPI as a dismantling adhesive that functions under mild conditions.
