Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201400711-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>We demonstrate the design and fabrication</bold> of tilted micropillar arrays on wrinkled elastomeric poly(dimethylsiloxane) as a reversibly switchable optical window. Upon re‐stretching the as‐prepared (opaque) film to the original pre‐strain, the grating color is restored and ∼30% transmittance is recovered. Further stretching beyond the pre‐strain makes the film more transparent. This process is fully reversible and repeatable for many cycles. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pghmfnj70v" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
