Stamp on a hot tin roof: A topographically patterned poly(dimethylsiloxane) (PDMS) stamp is heated to 50–220 °C. This stamp uses the heat energy as “ink” for microcontact printing (μCP) by inducing chemical cross-linking, decomposition, or other transformations. The hot μCP technique can pattern electrostatic charges on electrets by selective thermally stimulated discharge (TSD, see picture) or depolarization.
