What is polyacrylonitrile composed of?

Polyacrylonitrile (PAN) is a synthetic polymer with the linear formula (C3H3N)n. Although it is thermoplastic it does not melt under normal conditions, since it degrades before melting at above 300 °C. Almost all PAN resins are copolymers made from mixtures of monomers, with acrylonitrile as the main component.

What are nanofibers made of?

The Synthetic polymer nanofibers are made from nylon, acrylic, polycarbonate, polysulfones, and fluropolymers among other polymers. The biological polymer nanofibers are made from materials such as polycaprolactum, chitosan, polylactic acid, and copolymer of polylactic/glycolic acid among other biopolymers.

How is polyacrylonitrile synthesis?

Synthesis of polyacrylonitrile (PAN) is usually carried out with radi- cal catalysts, and in acrylic fiber industries, especially with redox catalysts. Anionic polymerization with butyl lithium and solid-state polymerization with y-ray irradiation1) have been attempted.

Where does polyacrylonitrile come from?

Polyacrylonitrile is a vinyl polymer, and a derivative of the acrylate family of polymers. It is made from the monomer acrylonitrile by free radical vinyl polymerization.

Is polyacrylonitrile a conducting polymer?

Polyacrylonitrile is a resin and does not fall in the family of conductive polymers. However Polyacrylonitrile has been used extensively as a part of ionic conducting polymer electrolyte showing the conductivity in the range of 10^(-2) S/cm.

What is the function of polyacrylonitrile?

Polyacrylonitrile is usually used to make other polymers like, carbon fiber. Fibers of polyacrylonitrile have been uses in hot gas filtration systems, outdoor awnings, sails for yachts, and even fiber reinforced concrete.

What is electrospinning process?

Electrospinning is a manufacturing technique involving electrostatic driven process used to create electrospun fibers. The diameter of these fibers typically ranges between tens of nanometers to a few micrometers.

Why do we do electrospinning?

This method is utilized to fabricate nanofibers of polymers, metals, ceramics, and composites. Nanoparticles are mixed with polymers and electrospun to produce scaffolds. Electrospinning is also used for the assembly of nanoparticles through the alignment with fibers and thus reduce the Gibbs Free energy [81].

What is polyacrylonitrile for?

Who discovered polyacrylonitrile?

It was only when chemist Dr. Herbert Rein (1899-1955) of IG Farben of Bitterfeld discovered in 1931 that PAN, obtained from a sample when visiting the Ludwigshafen factory, could be dissolved in the ionic liquid 1-benzylpyridinium chloride (1- Benzylpyridinium chloride) and transformed into fibers.

What is the purpose of polyacrylonitrile?
