PPV Fibers for Flexible Electronic Applications


Poly(p-phenylene vinylene)s (PPVs) are conductive, electroluminescent, conjugated polymers found in organic light-emitting diodes (OLED)s, field-effect transistors (FET)s, and photovoltaic cells [1-4]. Effectively spinning PPV-based materials into fibers would provide flexibility, strength, and reduced weight compared to other metal-based conductive composites. Bendable, conductive clothing, flexible keyboards and circuits, and electrical wiring from light-weight and organic materials could be realized. We are currently optimizing the spinning, production, and doping of PPV-based fibers and analyzing their tensile strength, crystallinity or orientation, and conductive properties [1, 5]. Future projects involve the design, synthesis, and spinning of novel PPV-type structures which are processable in ionic liquids, and the optimization of the conductivity in these types of polymer textiles for targeted organic electronic devices. Also, coating of PPV-based polymers onto various types of fibers and their conductivity will be evaluated.
