Abstract
The invention discloses a device and a method for realizing hierarchical experimental sample collection of electrospinning fibers by a controllable alternating magnetic field, and belongs to the field of electrostatic spinning. The problem that the efficiency and the precision of an electrospinning experiment are seriously limited by experimental conditions such as magnetic field space, voltage and frequency is solved. An alternating magnetic field motion control device causes and controls an annular alternating magnetic field generation device to move so as to enable the range of the formed alternating magnetic field to be controllable, a hierarchical electrospinning fiber collection device collects sprayed filaments under the action of the controllable alternating magnetic field, and the effect is that continuous collection of electrospinning fiber samples with multi-solution ratio or multi-parameter change is achieved.
Description
technical field [0001] The invention belongs to the field of electrospinning, and relates to a controllable alternating magnetic field to realize an electrospun fiber layered experimental sample collection device and method. Background technique [0002] Electrospinning technology is the simplest and most effective method for preparing nanofibers today. It has the advantages of low spinning cost, a wide variety of spinnable materials, and controllable processes. Nano-scale functional fiber products obtained by electrospinning have great demands in the fields of environmental protection, personal protection, biomedicine, and clean energy. However, the existing technology has not yet realized the full-chain industrial application of electrospun fibers, and in the electrospinning process, there are many process variables that affect the morphology and properties of electrospun fibers and are not easy to control. Among the technical means, there are factors that are difficult t...
