PolyFusionAgent: AI Foundation Model for Polymer Property Prediction and Inverse Design
Researchers have developed PolyFusionAgent, an interactive framework that combines a multimodal polymer foundation model (PolyFusion) with a tool-augmented design agent (PolyAgent). PolyFusion aligns complementary polymer views—sequence, topology, 3D geometry, and fingerprints—across millions of polymers to learn a shared latent space. This improves thermophysical property prediction and enables property-conditioned generation of chemically valid, structurally novel polymers. The framework addresses fragmentation in polymer representations, which has hindered AI-driven design in fields like energy storage and biomedicine.
