Abstract

An unusual polymer blend morphology of Voronoi Tessellations is discussed. AFM and phase-sensitive acoustic microscopy (PSAM) techniques are used for the purpose. Findings suggest that the congenitally entropy-driven phase separation process for polymer blend films may follow a quasi-Voronoi tessellation generation mechanism or engender a Voronoi tessellation stage. This propounds a newfangled way for modeling the phase-separation process during spin-coating.
