Question

How is Teflon prepared? State its application and what are Heteropolymers?

Answer 1

Hint :A polymer is a substance or material made up of numerous repeating subunits that make up very big molecules, or macromolecules. Both manufactured and natural polymers play crucial and pervasive roles in everyday life due to their wide range of characteristics. Polymers include anything from common synthetic plastics like polystyrene to biopolymers like DNA and proteins, which are essential for biological structure and function.

Complete Step By Step Answer:
Polytetrafluoroethylene (PTFE) is a tetrafluoroethylene fluoropolymer that has a wide range of uses. TeflonTM by Chemours, a DuPont spin-off, is the most well-known brand name for PTFE-based formulations. The chemical was first developed in 1938 by DuPont. Because it is a high molecular weight polymer made entirely of carbon and fluorine, PTFE is a fluorocarbon solid (at room temperature). As fluorocarbons display attenuated London dispersion forces due to their high electronegativity, PTFE is hydrophobic: neither water nor water-containing compounds wet it. The coefficient of friction of PTFE is one of the lowest of any substance.
Tetrafluoroethylene is polymerized by free radicals to create PTFE. The end result is
 $ nF_2C = CF_2 \to -(F_2C-CF_2)_n- $
Because tetrafluoroethylene can disintegrate explosively into tetrafluoromethane and carbon, specific polymerization equipment is necessary to avoid hot spots that might induce this harmful side reaction.
Applications:
Teflon is a non-stick surface. It's widely used in cookware, giving a non-stick surface for pans and pots all around the world. However, you've almost certainly come into touch with Teflon in other areas, sometimes without ever realising it.
Polish for your nails: Many nail polishes contain Teflon, which creates a smooth, crack-free surface.
Styling your hair Teflon is commonly used to coat straighteners and curling irons.
Protection for the carpet: Do you have a stain-resistant carpet? It's most likely made of Teflon.
Jackets that are waterproof: Do you have a Gore-Tex jacket in your closet? If that's the case, you're wearing Teflon.
Finishing paint and metal: That gleaming sheen on your car's paint? It's most likely Teflon.
Heteroploymer:
Heteropolymer is a polymer that is made up of multiple types of monomers, or it may be argued that the polymer is made up of two or more types of monomers. Proproteins are an example of a homopolymer. Heteropolymers are macromolecules that include many types of constituent units. Any synthetic heteropolymer sample has a large (practically infinite) number of distinct chemical components. Even at the same degree of polymerization, the molecules differ in chemical composition and structure, that is, in the proportions of various types of units and the pattern in which they are arranged.

Note :
Teflon's most versatile feature is that it may be used to cover almost anything without compromising the integrity or form of the item being coated. When considering the various applications of Teflon, it's vital to remember that Teflon may be utilised as a coating on virtually any material. Teflon can, for example, be used to coat dental fillings to keep them from clinging to neighbouring teeth. It may also be used as a coating for pipes to prevent corrosive substances from interacting with the metal. It also works well as a lubricant in situations when wet oil isn't viable.
