Thermo-mechanical behavior of self-assembled nanoparticle membranes

Abstract

Ultra-thin nanoparticle (NP) membranes are self-assembled hybrid materials that have attracted considerable interests. Monolayer membranes formed of simple dodecanethiol ligated gold NPs have mech. strength that comes mostly from weak non-covalent van der Waals interactions between ligands, yet they can free-stand over micron-size holes and have a Young's modulus on the order of several GPa. We will present our recent exptl.-theor. study on the thermo-mech. behavior of these membranes and reveal microscopic details relating to ligand rearrangement and dynamics that lead to their hysteretic mech. response. The results provide insight that can be useful in the development of new non-covalent self-assembled materials with tunable properties.
