Fabrication of Controlled Thermosensitive Polymer Nanopatterns with One‐Pot Polymerization Through Chemical Lithography

Brushing up: Poly(N-isopropylacrylamide) micro- and nanostructures can be grown on a gold substrate by grafting the polymer brush from an initiator-coated surface. The dependence of the brush height on the density of the initiator (controlled by the electron-beam doses) allows spatially defined polymer patterns with varying heights and unique surface topographies (see image) to be created in a single step.
