The morphology of gold particles ranged from microcrystals with well-developed crystal facets (AuMC) to vacuum-sputtered 5 nm gold nanoparticles (AuNP), 30 nm gold nanoislands (AuNI), and compact gold nanolayer (AuNL). The nucleated crystallization was studied by means of the improved sandwich method, which consisted in the controlled deposition of a homogeneous nucleant layer between ~ 100 μm PP films, followed by the careful thermal treatment and the evaluation of the nucleation activity by three independent methods: polarized-light microscopy, two-dimensional wide-angle X-ray scattering, and differential scanning calorimetry. It was demonstrated that the nucleating activity of gold strongly depended on its morphology.
