Autonomous multi-nozzle bubble-electrospinning device

Abstract

Provided is an autonomous multi-nozzle bubble-electrospinning device, relating to a static-spinning device.A bubble film is formed by providing introduced airflows. Meanwhile, bubbles can be autonomously pierced due to the fact that a metal electrode group performs reciprocating motion, promoting highly-efficient and steady injection of jet flows. Therefore, the autonomous multi-nozzle bubble-electrospinning device with fibers uniformly arranged is formed. The autonomous multi-nozzle bubble-electrospinning device is provided with a power source, a multi-sprayer top cover, a collection board, a liquid supply device, a bottom cover, an air pump, an air supply channel, an electrical telescopic push rod and a metal electrode group. The liquid supply device is connected with the multi-nozzle top cover through a hose. The interior of the upper end of the multi-nozzle top cover is provided with a liquid holding groove. The inner surface of the multi-nozzle top cover is provided with seven nozzles. The multi-nozzle top cover is arranged below the collection board. The metal electrode group is connected with the electric telescopic push rod which drives the metal electrode group to perform reciprocating motion up and down. The lower end of the multi-nozzle top cover is provided with a bottom cover. The air pump is connected with the bottom cover through the air supply channel. The bottom cap is provided with an air channel connector. A positive pole is connected with the liquid holding groove through a lead wire. A negative pole of the power source is connected to the ground. The connection board is connected to the ground.

Description

technical field [0001] The invention relates to an electrostatic spinning device, in particular to an autonomous multi-nozzle bubble electrostatic spinning device. Background technique [0002] The preparation of nanofiber materials by electrospinning technology is one of the most important academic and technical activities in the field of material science and technology in the world in the past ten years. Electrospinning technology has become a reliable method for preparing nanofibers due to its simple structure, low cost, high applicability, and controllable process. Electrospinning technology has high material compatibility, and a wide variety of nanofibers have been prepared using this technology, including organic, organic / inorganic composites, and inorganic nanofibers. [0003] At present, traditional electrospinning uses a single spinning nozzle for electrospinning, which produces only one jet, and the productivity is too low, only 0.01-0.1g / h, which greatly affects ...

Problems solved by technology

However, during the electrospinning process, the position of the standing wave will shift, the position and direction of the Taylor cone formation are not fixed, the uniformity of the jet and the formed fiber is low, and the interference between the jets is prone to occur
