Airflow and air bubble spinning device for preparing magnetic ordered nano composite material and method thereof

Abstract

The invention discloses an airflow and air bubble spinning device for preparing a magnetic ordered nano composite material and a method for spinning by utilizing the device. The airflow and air bubble spinning device comprises a liquid storage groove, an air bubble spraying pipe, a glass pipe, an air bubble generator, an air spraying pipe, an airflow generator, a receiving device arranged above the air bubble spraying pipe, a bracket platform which is fixedly connected with the receiving device, a magnetic control device mounted on the bracket platform and a liquid feeding device, wherein one end of the glass pipe is communicated with the air bubble generator and the other end of the glass pipe is communicated with the interior of the air bubble spraying pipe; the air spraying pipe is arranged on the side face of the air bubble spraying pipe and is connected with the airflow generator. In a spinning process, air bubbles are formed on the surface of a polymer solution containing magnetic nano-particles; after rising and breaking, the air bubbles are further subjected to stretching and thinning with airflow as power to form a lot of disordered magnetic nano fibers; and the disordered magnetic nano fibers do regular movement in a magnetic field control region generated by the magnetic control device to form a lot of ordered magnetic nano fibers and the ordered magnetic nano fibers are collected on the receiving device.
