Novel electrostatic centrifugal compound field continuous film spraying device

Abstract

The invention discloses a novel electrostatic centrifugal compound field continuous film spraying device, and relates to the technical field of film spraying devices. The novel electrostatic centrifugal compound field continuous film spraying device comprises a machining roller. A motor is fixedly arranged on one side of the machining roller. A support frame is fixedly arranged at the bottom of the motor. A first electrode plate is arranged on the top of the machining roller. A second electrode plate is arranged at the bottom of the machining roller. A connecting wire is fixedly arranged on one side of the first electrode plate. A high-voltage electrostatic generator is fixedly arranged on one end of the connecting wire. The inner of the machining roller is movably connected with a spraying roller. A plurality of spraying heads are arranged on the surface of the spraying roller. A first conveying pipe is fixedly arranged on one end of the spraying roller, and a centrifugal pump is fixedly arranged on one end of the first conveying pipe. By the action of an electrostatic field and centrifugal force, two-dimensional material slice layers in droplets are fully stretched and spread bythe combined action of the electrostatic field and the centrifugal force, and therefore, the novel electrostatic centrifugal compound field continuous film spraying device has the advantage that filmdefect structures caused by solvent evaporation are reduced so that highly ordered and dense film materials can be obtained.

Description

technical field [0001] The invention belongs to the technical field of film spraying devices, in particular to a novel electrostatic centrifugal composite field continuous film spraying device. Background technique [0002] Thin film materials are one of the key material forms in the development of modern industrial technology and cutting-edge application technology. Such as separation membranes, ion exchange membranes, heat conduction membranes, high barrier membranes, optical membranes, acoustic membranes, high dielectric membranes, etc.; at the same time, a large number of modern optoelectronic devices are also manufactured and function in the form of multilayer membranes, such as LED, OLED light emitting , thin film solar devices, etc. Two-dimensional materials are natural membrane materials, and the emergence of a large number of two-dimensional materials provides a new opportunity for the development of high-performance membrane materials. However, due to the limitat...

AI Technical Summary

Problems solved by technology

The two-dimensional materials in the film obtained by vacuum filtration and layer-by-layer self-assembly process have better orientation, but these two methods have low efficiency and are not suitable for the preparation of large-area thicker films

Although the other two processes have high film forming efficiency, the driving force to drive the directional self-assembly of two-dimensional materials is small and uncontrollable, and the arrangement of the two-dimensional materials inside the film is relatively chaotic.
