Provided herein is a device for forming a conductive film. The device includes a deposition device and an air supply. The deposition device is configured to form a wet film having conductive nanostructures and a fluid carrier on a web. The web is moved in a first direction while forming the wet film. The air supply is disposed at a side of the web and configured to apply an air flow onto the wet film. The air flow is directed onto the wet film in a second direction perpendicular to the first direction to reorient a direction of some conductive nanostructures in the wet film to define reoriented conductive nanostructures.

A pipe doping apparatus comprises a bucket assembly including a base and a bucket supported on the base and having an inside volume, a lubricating unit having at least one lubricant applicator inside the bucket; and a source of torque configured to rotate the bucket and/or the lubricating unit relative to a tubular. The apparatus may include a cleaning unit and/or a drying unit and the source of torque may be a fluid jet in either. At least one lubricant applicator may be retractable and may be actuated between a retracted position and an extended position by centripetal force. The apparatus may further include a positioning assembly supporting the base and the rotary bucket assembly and a controller connected to and controlling each of: the positioning assembly, the cleaning unit, the drying unit, and the lubricating unit.

A slit opening of a slit nozzle extends unidirectionally in a longitudinal direction from near the center of a circular substrate to near an outer edge of the substrate, and has a length in the longitudinal direction equal to or smaller than a radius of the substrate. When the slit nozzle discharges chemical onto the substrate, a rotary holder rotates the substrate and the slit nozzle relatively to each other about the center of the substrate. Accordingly, the chemical from the slit nozzle all adheres to a surface of the substrate to form an excellent liquid column and a chemical film on an almost entire surface of the substrate along the outer edge of the circular substrate. This yields satisfactory coating of the substrate with the chemical while waste chemical is suppressed.
