Abstract

Poly (dimethyl siloxane) with a compositional gradient was fabricated via a precision syringe pump setup. Stretching of the substrate and subsequent oxygen plasma oxidation resulted in a continuously changing wrinkle wavelength on the surface upon relaxation. This approch is a powerful tool
for designing gradient surfaces with tailored topography.
