What is the process of electrospinning?

Electrospinning is a fiber production method which uses electric force to draw charged threads of polymer solutions or polymer melts up to fiber diameters in the order of some hundred nanometers. The process does not require the use of coagulation chemistry or high temperatures to produce solid threads from solution.

What is the main process in making the carbon nanotubes?

Undoubtedly the most common method of carbon nanotubes synthesis, catalyzed chemical vapor deposition of hydrocarbons over a metal catalyst is a classical method that has been used to produce various carbon materials such as carbon fibers and filaments for over twenty years.

How carbon nanotubes are synthesized?

CNTs are synthesized by thermal CVD method by using hydrocarbon gas as carbon source. In this method, a quartz tube is placed inside a furnace maintained at high temperature (500–900°C) heated by RF heater.

How do you separate carbon nanotubes?

Physical Methods for Separation of Carbon Nanotubes Charged biological macromolecules are commonly separated by electrophoresis using gel in an electric field.

What is the function of electrospinning?

The electrospinning method is used to generate a nonwoven web of micro- or nanofibers. In this method, high voltage electricity is applied to the liquid solution and a collector, which lets the solution extrude from a nozzle forming a jet. The jet formed fibers during drying and deposited these on the collector.

Where is electrospinning used?

Because of the useful properties of e-spun fibers, many synthetic and natural polymers, including single and blended polymers, have been electrospun into fibers that can be employed in a variety of applications such as filtration and thermal insulation, and in the manufacture of protective clothing, sensors, conducting …

How do you make a nanotube?

We develop a new chemical route to prepare carbon nanotubes at room temperature. Graphite powder is immersed in a mixed solution of nitric and sulfuric acid with potassium chlorate. After heating the solution up to 70°C and leaving them in the air for 3 days, we obtained carbon nanotube bundles.

How do you synthesize carbon?

Typically, a feedstock of carbon black and metal catalyst particles is fed into the plasma, and then cooled down to form single-walled carbon nanotubes. Different single-wall carbon nanotube diameter distributions can be synthesized.

What does the chirality n/m denote for Carbon Nanotubes CNT )?

The pair of integers (n,m) is called the chiral index or just chirality. This implies that the structure of a single-walled carbon nanotube is completely determined by chirality.

What is electrospinning in tissue engineering?

Tissue engineering is an emerging multidisciplinary field that aims to regenerate damaged or lost tissues/organs of living organisms using a combination of cells and scaffolds [1,2]. Electrospinning is a spinning technique that uses electrostatic forces to produce fibrous scaffolds from biocompatible polymers.
