核心提示:灵活,清晰,极其坚固的石墨烯是热和电流的杰出导体,这使得它成为下一代电子设备的热门材料。在这方面,研究人员第一次使用石墨烯制造OLED电极。这可能会导致一系列新的组件,包括更好的触摸屏和更高效的太阳能电池。灵活,清晰,极其坚固的石墨烯是热和电流的杰出导体,这使得它成为下一代电子设备的热门材料。在这方面,研究人员第一次使用石墨烯制造OLED电极。这可能会导致一系列新的组件,包括更好的触摸屏和更高效的太阳能电池。

Core tips: flexible, clear, and extremely strong graphene is an outstanding conductor of heat and current, making it a hot material for the next generation of electronic devices. In this respect, the researchers used graphene for the first time to make OLED electrodes. This could lead to a series of new components, including better touch screens and more efficient solar cells.

附着到OLED(有机发光显示器)的电极约2cm x 1cm(1/2英寸 x 1/4英寸),使用化学气相沉积(CVD)工艺制造,其中甲烷和氢气被泵入真空室中,铜板被加热到800℃(1,472°F)。其中,两种气体之间发生化学反应,并当甲烷溶解到铜中时,其在表面上形成石墨烯原子。一旦该层充分形成,使整个装置冷却,施加保护性聚合物片,然后化学蚀刻掉铜以显露纯石墨烯的单原子层。

The electrode attached to OLED (organic light-emitting display) is about 2cm x 1cm (1/2 inch x 1/4 inch), manufactured by chemical vapor deposition (CVD) process, where methane and hydrogen are pumped into the vacuum chamber, and the copper plate is heated to 800 degrees (1472 degrees F). There is a chemical reaction between the two gases, and when methane is dissolved into copper, it forms a graphene atom on the surface. Once the layer is fully formed, the whole device is cooled, the protective polymer is applied, and the copper is chemically etched to reveal the single atomic layer of the pure graphene.

Fraunhofer有机电子学,电子束和等离子体技术FEP项目负责人Beatrice Beyer博士说,“这是极苛刻材料研究和集成的真正突破。虽然这不是第一个在其构造中使用石墨烯的柔性显示屏,但它首次引入OLED技术,向全色屏幕和快速响应时间迈出一大步。”

"This is a real breakthrough in the research and integration of extremely demanding materials," said Dr. Beatrice Beyer, director of FEP project of Fraunhofer organic electronics, electron beam and plasma technology. Although this is not the first flexible display screen to use graphene in its construction, it introduced OLED technology for the first time, taking a big step towards panchromatic screen and fast response time.

从导体,到超级电容器,太阳能电池和一系列其他电子设备,石墨烯被广泛应用,这种材料制成的显示屏改善光伏电池,可穿戴设备,柔性纺织品和医疗器械的寿命,耐用性和可用性,这项研究可能导致这些领域在不久将来有突飞猛进的发展。

From the conductor to the super capacitor, the solar cell and a series of other electronic devices, graphene has been widely used, such materials display improved photovoltaic cell, wearable devices, flexible textile and medical equipment service life, durability and usability, this study may lead to these areas in the near future there is rapid development.
