In this work, we report a simple and scalable solution-based method to deposit nanoscale material thin films. We have demonstrated uniform thin films fabricated by a flash dry deposition method, including carbon nanotubes and polyaniline nanofibers. The films are electrically uniform across an entire area of 8 inches by 8 inches in size. This method can be applied to other nanoscale materials and substrates or nanomaterial multilayer structures if the correct solution-substrate interface

... tion is achieved. In the end, we use this method to deposit CNT thin films on an unusual substrate-the inner side of thin glass tubing. Such transparent and conductive coating in glass tubing is not possible with traditional indium tin oxide sputtering and allows for a novel design of electrowetting devices.
