Research summary
Solution-processed single-layer graphene oxide films were spin-coated onto quartz and subjected to several reduction treatments to assess their suitability as transparent conductors; thermal graphitization was the most effective treatment, yielding sheet resistance of 10^2-10^3 ohm/square at 80% optical transmittance for 550 nm light, supporting the use of solution-processed graphene oxide films as transparent electrodes [1]. A 25th-anniversary review traces the development of electronic skin (e-skin), framing it as a large-area network of flexible, stretchable, robust sensing devices inspired by the integrated network of tactile and thermal sensors in human skin. The review discusses motivations for the field including autonomous robotics and biomimetic prosthetics, and surveys design considerations and progress toward integrating multiple sensing functionalities in large-area implementations [2]. Solution-cast regioregular poly(3-hexylthiophene) was characterized as a thin-film field-effect transistor channel material, achieving field-effect mobilities of approximately 0.045 cm^2/V s in accumulation mode and 0.01 cm^2/V s in depletion mode together with on/off current ratios greater than 10^3. Film quality and mobility depended strongly on the choice of casting solvent, and post-deposition treatment with ammonia or heating to 100 degrees C under nitrogen improved the on/off ratio without sacrificing mobility, demonstrating that a soluble, processable conjugated polymer could deliver transistor characteristics suitable for thin-film device work [3].
