| Abstract Scope |
Supercrystalline nanocomposites are a rising category of nanoarchitected materials, resulting from the self-assembly of functionalized nanoparticles into long range order architectures. Being typically explored in the field of chemistry, their mechanical behavior is largely unexplored — a lack of information that hampers their multiple potential functional applications (in optoelectronics, catalysis, energy transfer and storage, and more). Nanoindentation is ideally suited to tackle this issue. We present here a thorough nano and micro-mechanical characterization of ceramic-organic supercrystalline nanocomposites. An extreme boost in strength, hardness and stiffness is observed after inducing the crosslinking of the organic phase. Time-dependent behavior is observed via creep and fatigue studies. Many fundamental questions are addressed, inspiring solutions to fine-tune the mechanical behavior of these promising new generation of nanostructured materials. |
