World’s First Demonstration of Structural Adhesion with MOF/CPs

A study conducted by Izuru Miyazaki et al. was published in Small.

Metal–organic frameworks /coordination polymers (MOF/CPs) have been actively researched in recent years; however, their applications have been limited to functional materials such as gas adsorbents and catalysts. Miyazaki et al. demonstrated that MOF/CPs could be used as structural adhesive materials for metal substrates. Accordingly, they proposed an adhesion process in which a gel-containing MOF/CP precursor was pressure-sintered. Unlike resin materials, which are often used as adhesives, MOFs/CPs can exhibit small thermal–expansion behavior (comparable to that of metals). Further, they are expected to achieve highly reliable adhesion, even under temperature fluctuations. It is anticipated that this research will lead to the development of a new academic field of MOF/CP adhesives.
