Article Synopsis
- A new numerical simulation method called SDNMR-WEBFIT is introduced for analyzing proton spin diffusion NMR, utilizing the Levenberg-Marquardt algorithm and a pseudo-2D diffusion model.
- This method accurately quantifies the dynamic heterogeneity in multiphase polymer systems, measuring key parameters like spin-lattice relaxation time, proton density, lamellar thickness, and spin diffusion coefficient for each component.
- It has been successfully applied to various materials, including semi-crystalline polymers, block copolymers, and plasticized semi-polymers, enhancing our understanding of their structural dynamics.
