Structured metal films on silicone elastomers

The ability to control surface morphology at nano- and micrometre length scales is required in many applications. It has previously been demonstrated that surface wave patterns are spontaneously generated when heated, layered metal-on-silicone materials are cooled, because of the stress that builds up between two materials of different modulus and coefficients of thermal expansion. We have examined the behaviour of metals sputtered on silicone …
