A novel tool to determine nucleus density in colored system with NA

/ department of mechanical engineering Introduction Adding nucleating agent (NA) into a crystallizable polymer system is a common way, applied in polymer industry, to control crystallization and tailor mechanical and optical properties of products. These properties are closely related to the resulting nucleus density. For colored NA systems, nucleus density becomes too large and subsequently changes the optical properties, which will both make quantification of nucleus density difficult with optical microscopy. The aim of this project is to develop a new method to determine the nucleus density for colored NA systems with rheometry.
