Rapid and Versatile Photonic Annealing of Graphene Inks for Flexible Printed Electronics

Data corresponds to the demonstration of photonic annealing to cure inkjet-printed graphene patterns. Few-layer graphene flakes are produced by liquid-phase exfoliation and stabilized by ethyl cellulose to formulate inks suitable for inkjet printing. Photonic annealing is applied as an alternative to thermal annealing for rapid processing and integration on temperature-sensitive substrates. Characterization of the materials using atomic force microscopy, Raman spectroscopy, thermal gravimetric analysis, and electrical measurements reveals suitable properties for application in printed and flexible electronics.

本数据集对应光子退火（photonic annealing）固化喷墨打印（inkjet printing）石墨烯图案的工艺演示。本研究通过液相剥离（liquid-phase exfoliation）法制备少层石墨烯片（few-layer graphene flakes），并以乙基纤维素（ethyl cellulose）对其进行稳定化处理，以此调配得到适用于喷墨打印的油墨。光子退火作为热退火（thermal annealing）的替代方案，可实现快速加工，并能够在温敏基底（temperature-sensitive substrates）上完成集成。通过原子力显微镜（atomic force microscopy）、拉曼光谱（Raman spectroscopy）、热重分析（thermal gravimetric analysis）与电学测试对材料进行表征后可知，该材料具备适用于印刷柔性电子器件的性能。DOI: 10.1002/adma.201502866
