A dip coating apparatus includes a liquid tank containing paint and a hanging tool for dipping into or removal from the liquid tank. The hanging tool includes a hollow frame, a first and second rack, and two first hanging frames. The hollow frame has a first and second strip. The first and the second racks are disposed in the hollow frame and connected to the first and the second strips. Each of the first hanging frames includes a first top strip connected to the first rack, a first bottom strip connected to the second rack, and a first lateral strip connected to the first top strip and the first bottom strip. Each first lateral strip forms an obtuse angle with the corresponding first top strip and an acute angle with the corresponding first bottom strip. Each first lateral strip includes a first top hook and a first bottom hook.

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 method for applying a multi-layer coating includes passing a substrate through a nip defined by two rolls to apply a first thickness of a first liquid coating material, applying a second liquid coating material on the first liquid coating material having the first thickness as applied by passing through the nip, and controlling a thickness of the applied second liquid coating material.

An apparatus for coating an inner surface of a medical tube includes a housing, an injection unit, a drying unit, and a supply unit. The housing defines an external shape of the apparatus and provides a workspace. The injection unit is positioned in an upper portion of the workspace and injects a coating fluid into a medical tube connected to a nozzle tip formed at a lower end thereof. The drying unit is positioned on the injection unit and dries the coating fluid introduced into the medical tube. The supply unit positioned in a lower portion of the workspace and collects a residual coating fluid discharged from a lower end of the medical tube and transfers the collected residual coating fluid to a supply valve of the injection unit. The apparatus can easily, uniformly, and efficiently coat the inner surface of a long medical tube such as a catheter.
