Design of Recyclable Plastics with Machine Learning and Genetic Algorithm

Episodes 2024 16 citations

AI summary Read the abstract

Researchers used a genetic algorithm paired with machine learning models to design nearly one million candidate ring-opening polymerization polymers, identifying several that match polystyrene's thermal and mechanical properties while being chemically recyclable, offering a promising AI-guided path toward more sustainable plastic materials.

Polymers

We present an artificial intelligence-guided approach to design durable and chemically recyclable ring-opening polymerization (ROP) class polymers. This approach employs a genetic algorithm (GA) that designs new monomers and then utilizes virtual forward synthesis (VFS) to generate almost a million ROP polymers. Machine learning models to predict thermal, thermodynamic, and mechanical properties─crucial for application-specific performance and recyclability─are used to guide the GA toward optimal polymers. We present potential substitute polymers for polystyrene (PS) that achieve all property targets with low estimated synthetic complexity.
