Polymer nanocomposites have shown promising results as a sustainable alternative to the modern energy storage problem. The structures of these nanocomposites within the polymer matrix play a major role in controlling their applicable properties. However, qualitative descriptors are often used that are difficult to integrate into numerically based analysis. To address this challenge, this project attempts to “score” degrees of aggregation in polymer nanocomposites on a continuous scale based on 3D reconstructions of these systems via CREASE.
