Abstract

Data-driven and machine learning (MLmachine learning)-based approaches have recently been employed in materials science to enable rapid predictions of material properties. Polymers, known for their affordability and highly customizable properties, are widely utilized in various technological applications. However, their complex chemical composition and morphology present challenges in their development. The fusion of ML algorithms with vast data resources has opened new avenues for progress in polymer science and engineering. Polymer informaticsinformatics has emerged as a field aimed at accelerating the performance and optimization of process for novel polymerspolymers through MLmachine learning models trained on reliable data, as these materials exhibit unique physical behaviors across vast length-time scales, particularly in nonequilibrium glassy states, where experimental depictions and simulations are expensive and challenging. With the continuous growth of existing databases, the emergence of new data resources, and ongoing advancements in MLmachine learning algorithms, the landscape of informatics in polymers is becoming increasingly systematic and broadly applicable. One notable development in this field is Polymer GenomePolymer Genome, an informatics program, aimed to predict various critical desired polymer properties. This platform, trained on a large polymer dataset, employs surrogate MLmachine learning models that correlate key polymer features with their properties, leveraging high-throughput density functional theorydensity functional theory (DFT)) alongside experimental data sources from literature and established databases. Despite its robustness and predictive power, these models still face limitations in designing materials that meet specific property or performance objectives.
