Stimuli-responsive, mechanically-adaptive polymer nanocomposites

Stimuli-responsive nanocomposites composed of functional nanoparticles that are embedded within polymer matrices have begun to attract much attention as a new generation of mechanically-adaptive materials. These systems exhibit properties that exploit the influence of the filler beyond static mechanical reinforcement. The underlying mechanisms of these new nanomaterials typically involve an external stimulus that impacts the composite material, altering its bulk mechanics. In this feature article, the key components currently being utilized to create polymeric nanocomposites with morphing mechanical properties are discussed, along with potential applications that provide the motivation for the development and investigation of such materials.
