Abstract Details

2014, Master of Science, University of Akron, Polymer Science.
Electrospinning is a versatile tool to fabricate polymer nanofibers. It is over other techniques due to the low cost, fast speed, simple procedures and ambient operation conditions. It is the most high-throughput technique to produce fibers with nanometer range diameters. The electrospun insulate polymer fibers can be converted to conductive materials by thermal annealing, doping or patterning, which provides alternative ways to fabricate transparent electrode. The commercial transparent electrodes, which have both good conductivity and considerable transparency, are made of indium-tin-oxide (ITO). It plays essential role in the many optoelectronic devices such as solar cells, displays and touch screens. However, ITO is expensive and brittle, limiting their usage in flexible electronics. In this research, conductive metal films are patterned into transparent metal nanowire networks by using electrospun fibers as a mask. Both the transmittance and sheet resistance (6 ¿/¿ at 83% transmittance and 24 ¿/¿ at 92% transmittance) of the metal nanowires based electrode out-perform commercial indium doped tin oxide (ITO) electrodes. The metal nanowire based transparent electrodes were fabricated on both rigid glass and flexible polyethylene terephthalate (PET) substrates. In addition to state of art performance, the transparent electrodes also exhibit outstanding toughness. This film is flexible, transparent and provides good conductivity. They can withstand repeated scotch tape peeling and various bending tests. The method for making the metal nanowire is scalable and a touch screen on flexible substrate is demonstrated. The further improvements of the transparent film are discussed.
