  • Method of creating wrinkle structures for reversible and irreversible applications
    Patent number: 8585848
    Abstract: Methods of creating reversible and irreversible wrinkle structures are provided. A shape memory polymer is heated to a transition temperature and cooled while applying a first force. A rigid film layer is secured to the shape memory polymer to form a bilayer. The original shape of the shape memory polymer is recovered to create a first set of wrinkles in the rigid film layer. The bilayer is heated to the transition temperature and a second tensile force is applied to create a second set of wrinkles in the rigid film layer.
    Type: Grant
