Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold> <italic>Gradient growth</italic> </bold> of poly(NIPAM) brushes from an initiator‐modified substrate surface was achieved by electrochemically mediated atom‐transfer radical polymerization (eATRP). In their Communication on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">page 3922 ff., </ext-link> S. Inagi et al. show that setting the surface close to a bipolar electrode results in a potential gradient, which leads to a concentration gradient of the Cu^I polymerization catalyst on the substrate. The polymer brushes could be fabricated in three‐dimensional gradient shapes with control over thickness, steepness, and modified area.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjbpjj6ws" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
