Electrospinning collector. The electrospinning process is known as a multidisciplinary process that includes areas such as fluid dynamics, polymer chemistry, physics, electrophysics, mechanical engineering and textile engineering.
electrospinning drum collector
It basically consists of three main parts. High-voltage power supply, power supply (syringe, metal needle, etc.), collector plate (circuit board, rotating cylinder, etc.). With the electrospinning process it is possible to obtain surfaces derived from polymers made of nanofibers with diameters ranging from a few microns to less than 100 nm.

Our electrospinning machine is designed for R&D and laboratory study and multi-needle nanofiber production. It is designed for the development of nanofiber-based products in many industrial sectors such as textile and air filter, chemical, defense, construction, medical, pharmaceutical and agricultural industries.

Polymer solution, process parameters and environmental parameters influence the manufacturing process of nanofibers by electrospinning processes. These parameters can be grouped under three main headings.
cells seeding collector electrospin electricuted
The molecular weight of the polymer is an effective parameter for the structure of the fibers produced.
collector choice for electrospinning
The concentration of the polymer solution is an important parameter affecting the fabrication process of nanofibers by electrospinning. With increasing concentration of the polymer solution used, polymer particles in micro and nano sizes are formed.
collector less electrospinning
If it is increased further, vortex structures are observed. When the concentration is reduced, electrospray occurs instead of electrospinning.
collector used in electrospinning to do carbonization
When the right concentration is provided and other parameters are increased, the production of ideal nanofibers is achieved.
collectors of electrospinning
In general, molecular weight indicates the viscosity of polymer chains in solutions. By increasing the molecular weight, smooth fiber and microstrip are obtained.
electrospinning collector design
The viscosity of the polymer solution plays an important role in determining fiber morphology. It has been proven that continuous and smooth fibers cannot be obtained with very low viscosity (Ismail et al., 2019).
electrospinning collector distance
The viscosity of the polymer solution used can be changed by adjusting the concentration of the polymer in the solution. The viscosity range of different polymer or oligomer solutions used in the electrospinning process is different.
electrospinning collector material
The surface tension is a dominant factor for the low viscosity of the solution used. Only fibers with a pearl structure are formed. When using a solution of suitable viscosity, continuous fibers are formed.
The surface tension of the fiber solution produced in the electrospinning process also plays a very important role. Different solvents can contribute to different surface tensions. At a fixed concentration, the surface tension of the solution decreases and the beaded fibers formed can be replaced by smooth fibers.
Electrospinning gel collector
The conductivity of the solution used in the preparation is determined depending on the type of polymer and the type of solvent. In general, natural polymers are known to increase the chargeability of the polymer beam with more ions under higher voltage under electric field and produce weak fibers.
electrospinning liquid collector
The adjustment can be made by adding ionic salts such as KH2PO4, NaCl, etc. to impart electrical conductivity to the electrospinning solution (Matabola and Moutloali, 2013).
electrospinning rotating collector
The voltage applied in the system plays a very important role in the electrospinning process. By applying a high voltage, the polymer solution is electrically charged with a specific electrical conductivity.
electrospinning système collector
As the applied voltage increases, the diameter of the fiber produced decreases due to the increase in electrostatic repulsive forces on the die. This reduces the pearl structure. However, at very high voltages, increased jet instability can be observed as the Taylor cone collapses into the nozzle.
how does rotating collector affect fiber diameter electrospinning
As a result, increased bead formation can be observed. As the voltage increases to a certain level, beading decreases while the bead shape changes from spherical to spindle-shaped.
melt electrospinning collector distance
However, as the voltage is further increased, the spheres again approach the spherical shape. That is, the applied voltage must have an upper limit.
novel method of electrospinning rotating dual electrode collector design
The high voltage applied by the power supply to the main components in the electrospinning process can result in increased beading after the Taylor cone is pushed back into the nozzle.
rotating collector electrospinning
Increasing the tension up to a certain level will produce smooth fibers, while increasing it further can result in structural degradation.
rotating continual collector electrospinning
In addition, the surface tension and the viscosity of the solution can be adjusted by changing the solvent mixture and the mass ratio.
using textiles as an electrospinning collector
Sometimes it is possible to obtain a high conductivity of the solution by using an organic acid as a solvent.
why collector is grounded in electrospinning?
Solution Flow Rate: The flow rate of the polymer solution in the syringe to the manifold is another important process parameter. In general, a lower flow rate is recommended because the polymer solution takes time to polarize. If the flow rate is too high, large diameter fibers will ball up.
