Self-folding membranes

POSTER

Abstract

I consider an elastic membrane treated so that one side is solvophobic, and the other is solvophillic. The membrane crumples itself into a complex, compact form under specific, strong solvent interactions. The form of the collapsed membrane is strongly affected by scoring a tessellating network of ordered creases into the fabric of the membrane. The ordered tessellated collapsed structure exhibits several interesting mechanical properties, such as a traction-induced spontaneous curvature and a negative Poisson ratio.
