We present a new class of rapid solution process for fabricating highly uniform chemically derived graphene and carbon nanotubes (CNT) thin films with control over the thickness on the subnanometer-scale. The film deposition directly on rigid or plastic substrates is driven by dragging a meniscus of microliter graphene oxide (GO) or CNT suspension trapped between two plates – meniscus dragging deposition (MDD) technique. The fine tuning of the optoelectronic properties of the conducting thin films is achieved by simply varying the number of deposition, carbon nanomaterial concentration, dragging speed, and angle between two plates. This coating technique is simple, inexpensive, and easy to scale for large-area thin films used as transparent electrodes with a significant reduction of the material consumption. The deposition of highly uniform thin films enables the simple micropatterning of graphene and CNT with high resolution for its application to optoelectronic devices. |
