Phase-separated PS/PVAC blend exhibiting nanoscale compositional heterogeneity and distinct IR absorption characteristics from each polymer component.

PiFM imaging at 1250 cm⁻¹ selectively enhances the PVAC-related vibrational response, clearly visualizing the chemical distribution and domain contrast across the heterogeneous blend.
