Phase Diagram

Caption: A phase diagram shows the amount of compressive strain needed to create wrinkles, creases and folds in rubbery materials. The purple area denotes the wrinkle state and the aqua areas are two crease states. The spot marked "R" denotes folding. The findings will help engineers control these states and use them in structured nanomaterials.
