Direct Laser Processing and Functionalizing Polymer Composites for an On-Demand, Programmable, Recyclable Device Platform

Abstract

Embodiments relate to flexible electronic devices and associated fabrication methods that employ direct laser scribing to create porous laser-induced graphene (LIG) networks on an adhesive, stretchable polymer composite. In particular, the method includes forming a mixture including one or more polymer precursors capable of LIG, one or more elastomeric prepolymers, and one or more adhesion-promoting additives; curing the mixture to form a polymer composite; and laser scribing the polymer composite to pattern an integrated LIG network. The resulting LIG network can be selectively functionalized with nanomaterials, enzymes, or other agents to enable a variety of functions.
