Thermal Curing of Polymers at the Nanoscale by Optothermal Manipulation of Gold Nanoparticles — •Jakob Lenz, Christoph Maier, Michael Fedoruk, Theo Lohmüller, and Jochen Feldmann — Photonics and Optoelectronics Group, Ludwig-Maximilians-Universität München, Amalienstraße 54, München

Light absorbed by small gold nanoparticles is very efficiently converted into heat on a picosecond timescale. Single particles can thus be used as a heat source on a very confined, nanoscopic area. Here we demonstrate how these properties can be utilized to trigger and control the heat induced polymerization reaction of thermosetting polymers at the nanoscale and show how this approach can be applied to fabricate polymer nanostructures such as particles and nanowires with a resolution well below the diffraction limit. Overall, this approach represents a new way of controlling polymerization reactions at the nanoscale by taking advantage of plasmonic heating.
