Abstract
An apparatus and method for producing oriented polymer films are disclosed. The apparatus includes a curved enclosure configured to rotate and a flow obstacle. The curved enclosure has an interior volume with an opening at one end. The flow obstacle extends through the opening and interior volume, with one end rigidly coupled to a mounting plate. The flow obstacle's position is adjustable to contact the interior surface of the curved enclosure, defining a gap between them. The method involves introducing a material into the curved enclosure, adjusting the flow obstacle's position, and rotating the curved enclosure to generate an extensional flow within the material. The apparatus and method may be used for producing two-dimensional polymer films and can incorporate features such as inert gas flushing, heating systems, and various blade configurations for the flow obstacle.
