Fabrication and Characterization of Thin Films of Single-Walled Carbon Nanotube Bundles on Flexible Plastic Substrates

摘要

We describe an extremely simple method by which one can obtain thin, strongly adherent films of single-walled nanotube (SWNT) bundles on flexible, transparent plastic substrates such as poly(ethylene terephthalate) (PET: "overhead transparency"). These films show low sheet resistance, >80% optical transparency and robust flexibility, e.g., they can be bent and folded to a crease while retaining full electrical connection across the crease.1 We believe this could open new opportunities in the design and development of next-generation transparent optoelectronic devices.
