Wearable electronic devices are a goal of current microelectronic research. These devices will require new flexible substrates as well as new processing methods to fabricate the devices. We demonstrate a novel versatile process of forming conductive patterns on various types of substrates utilizing polyelectrolyte multilayer (PEM) coatings and microcontact printing (µCP). The conductive materials employed for these studies are electrolessly deposited metals and graphite nanoplatelets (i.e., exfoliated graphene sheets). Optical microscopy, quartz crystal microbalance, atomic force microscopy, ellipsometry, electron microscopy, energy dispersive x-ray spectroscopy and impedance spectroscopy were used to analyze the selectivity and structure of the fabricated patterns.
