Parallel laser fabrication of film-embedded microstructures using reusable functionalized template
B Kang and SKD Nath and HC Kim and SG Kim, JOURNAL OF APPLIED PHYSICS, 115, 063103 (2014).
This study proposes a new parallel mass-production method for obtaining microstructures embedded in flexible films, utilizing a laser-processed reusable functionalized template and a laser-induced adhesive transfer. This physical shape-free template can be cost-effectively fabricated by means of the laser-induced plasmonic defunctionalization of a self- assembled monolayer. The resulting metal nanoparticle microstructure, deposited self-selectively on the template, is transferred to a flexible film by a photo-induced instantaneous interfacial adhesion film in parallel; this process being optimized using molecular dynamics simulations. This method is demonstrated to be capable of the high- efficiency and eco-friendly production of high resolution and durable microstructures in flexible films, using a reusable template to eliminate material waste. Moreover, key design parameters such as the resolution, thickness, type, and shape of microstructures can be actively changed. (C) 2014 AIP Publishing LLC.
