| 摘 要： | 采用化学方法制备直径约100μm的超大尺寸氧化石墨烯,利用Langmuir-Blodgett自组装法将其逐层沉积于基体表面,制备透明导电薄膜。经过高温还原后,平坦、紧密排列结构的石墨烯薄膜具有高导电性及透明度。在86%的透明度下,获得的表面电阻为605-/sq,此光电性质优于用化学气相沉积法在Ni表面生长的薄膜。该方法具有易操作、成本低、便于工业化大规模生产等优势。

| Abstract: | Monolayer ultra-large graphene oxide (UL-GO) sheets with diameter up to about 100 μm were synthesized based on a chemical method. Transparent conductive films were produced using the UL-GO sheets that were deposited layer-by-layer on a substrate by the Langmuir-Blodgett (L-B) assembly technique. The films produced from UL-GO sheets with a close-packed flat structure exhibit exceptionally high electrical conductivity and transparency after thermal reduction. A remarkable sheet resistance of 605 -/sq at 86% transparency is obtained, which outperforms the graphene films grown on a Ni substrate by chemical vapor deposition. The technique used to produce transparent conductive films is facile, inexpensive and tunable for mass production. |
