文摘

The morphology and electrical properties of gold nanoparticles (AuNP) layer vacuum-deposited onto spin-cast thin films of poly(3-hexylthiophene), P3HT, were studied. The electrical conductivity was measured during temperature cycling and related to the morphology of the same composite structures, which was monitored by transmission electron microscopy (TEM) and extra-high resolution scanning electron microscopy (XHR SEM). Comparison to the analogous polystyrene/AuNP layers was made to distinguish the role of the polymer support on the morphology and electrical properties of the nanoparticles assembly. Gold deposited in a very thin layer formed a nanoparticles-like island structure with the morphology depending on the effective thickness of the deposited layer and on its subsequent thermal treatment. A stabilizing effect of the thiophene–gold interaction on the nanoparticles morphology was observed.
