Abstract

Transparent, flexible conducting films were fabricated by using a metallic grid and graphene hybrid film. Transparent electrodes using the hybrid film and transparent substrate such as glass or polyethylene terephthalate (PET) films were assembled. The sheet resistance of the fabricated transparent electrodes was as low as 3 Ω/◻ with the transmittance at ∼80%. At 90% transmittance, the sheet resistance was ∼20 Ω/◻. Both values are among the highest for transparent electrode materials to date. The materials used for the new hybrid electrode are earth-abundant stable elements, which increase their potential usefulness for replacement of indium tin oxide (ITO) in many applications.

摘要

采用金属网格和石墨烯混合薄膜制备了透明、柔性导电薄膜。组装了使用混合薄膜和透明基底（如玻璃或聚对苯二甲酸乙二醇酯（PET）薄膜）的透明电极。所制备的透明电极的方阻低至 3 Ω/□，透光率约为 80%。在 90%的透光率下，方阻约为 20 Ω/□。这两个值都是目前透明电极材料中最高的之一。新的混合电极使用的材料是丰富且稳定的元素，这增加了它们在许多应用中替代铟锡氧化物（ITO）的潜在用途。
