Abstract Scope |
We present a graph neural network framework to assess particle growth kinetics in different materials systems. We define a metric for similarity, quantitatively accounting for particle eccentricity, radial growth rate, and final size between particles. Using a graph neural network architecture, we predict the similarity between particles across various materials systems at different stages of growth. We design our training dataset by choosing particle pairs that obey established growth kinetics models and using domain expertise. Based on pairwise particle similarity analysis, we infer the overall behavior of materials systems using various machine learning algorithms. We implement this framework for fluoroelastomer films undergoing crystallization due to thermal aging. We track the pairwise similarity for crystallite pairs at different times and correlate them to growth kinetics models. As a result, we can quantify particle behavior in a pairwise fashion, leading to improved statistics. |
