Strong Means Slow:Dynamic Contributions to the Bulk Mechanical Properties of Supramolecular Networks

摘要

The desire to control rationally,through small-molecule synthesis,the properties of bulk materials has led to supramolecular approaches to,for example,polymers,strong and weak organogels,amphiphilic assemblies,and liquid crystals.In these materials,specific and well-defined interactions between molecules contribute to bulk material properties on two levels:structure and dynamics.Although the dynamic nature of the defining interactions is often the attribute that distinguishes supramolecular materials from their covalent counterparts,direct mechanistic studies of the molecular contributions to the dynamic properties of materials are less abundant than structural studies.
