A line graph titled Temperature-resolved long-term degradation predictions using the PINN. The horizontal axis represents Time in days, ranging from 0 to 3500. The vertical axis represents Volume-averaged property retention P avg(t), ranging from 0.2 to 1.0. The graph includes three lines representing different temperatures: 423 K in blue, 453 K in orange, and 483 K in green. All lines show a downward trend, indicating a decrease in volume-averaged property retention over time. The blue line (423 K) shows the slowest decline, followed by the orange line (453 K), and the green line (483 K) shows the steepest decline.Temperature-resolved long-term (10-year) degradation predictions obtained using the trained PINN. The curves correspond to volume-averaged property retention for aging temperatures of 423 K (blue), 453 K (orange), and 483 K (green). The progressive divergence between curves reflects Arrhenius-type thermal activation and confirms the physical consistency of the long-term predictions
