Physics-Informed Neural Networks in Polymers: A Review. [PDF]

Polymers (Basel)
The modeling and simulation of polymer systems present unique challenges due to their intrinsic complexity and multi-scale behavior. Traditional computational methods, while effective, often struggle to balance accuracy with computational efficiency, especially when bridging the atomistic to macroscopic scales.
