Abstract
Photopolymerization, crucial for creating functional materials, lacks robust techniques for describing nanoscale morphology evolution. This study uses in situ, real-time monitoring to quantify these transformations. It reveals that initial precursor structures significantly impact the final morphology and properties due to heterogeneities in molecular mobility during curing. Local physical arrest, from cross-linking and vitrification, determines the heterogeneity length scale (10–200 nm).
