Predicting the curvature of bilayer structure by theoretical modeling at different temperatures. a) Schematic showing the shape changes of bilayer structure upon heating. b) Photographic images of the bilayer structure. c) Prediction of the curvature from our elastic model. d) Comparison of the radius of curvature between theoretical and experimental results as a function of temperature (upper bound and lower bound of the model are from the errors of input parameters from measurements). e) Curvature difference between elastic and plastic models as a function of temperature.
