Nothing stuck to Mafia boss John Gotti who evaded justice for years by bribing
and threatening jurors and witnesses. That earned him the name
the Teflon Don after one of the slipperiest
materials on Earth. Teflon was in the spacesuits the Apollo
crew wore for the moon landing, in pipes and valves used
in the Manhattan Project, and maybe in your kitchen as the nonstick
coating on frying pans and cookie sheets. So what is this slippery solid,
and why doesn’t anything stick to it? Teflon is a brand name for
polytetrafluoroethylene, or PTFE. It was stumbled upon accidentally in 1938
by a 27-year-old American chemist named Roy Plunkett while he was trying to develop
a non-toxic refrigerant fluid for DuPont, a chemicals company. The strange, white substance that formed
inside his lab canister was chemically inert, meaning it wouldn’t react
with other substances. It also had an extremely
low coefficient of friction, making other materials slide right off it. Teflon’s properties make it perfect
when you need something slippery, chemical resistant, or waterproof, which means it has a lot of applications. It can be found all over the place, as a coating on raincoats, industrial ball bearings, artificial joints, circuit boards, and even the Rocky Mountains-themed roof
of the Denver International Airport. The incredible properties of PTFE
come from its molecular structure. It’s a polymer, meaning it’s made of long chains of
repeating units of atoms strung together. A PTFE chain has a backbone
of carbon atoms, each of which is attached
to two fluorines. The fluorine atoms surround the carbon
like armor, spiraling around the chain, and the bond between carbon and fluorine
is incredibly tight. Like a couple that ignores everyone
except each other, carbon and fluorine interact so strongly that the normal, intermolecular forces
that help substances stick to each other don’t stand a chance. Even the famously adhesive feet of geckos
usually can’t get a grip. But wait! If PTFE doesn’t stick to anything, how can it be so firmly attached
to something like a pan? One method involves sandblasting the pan or etching it with chemicals
to make it rough. Then, a special primer is applied,
which acts like glue. Its exact composition is a trade secret
guarded by each manufacturer. The pan is sprayed with liquid PTFE and heated to around
800 degrees Fahrenheit. The layers then solidify into
a smooth, slick coating. When you later cook eggs
in this PTFE-coated pan, the extra tight carbon-fluorine bonds just ignore the water and fat and protein
molecules in the eggs. Without those interactions, the food just slides around
without sticking. You might wonder if it’s safe to cook
in a PTFE-coated pan. The answer is yes, if you’re careful. PTFE is stable at moderate temperatures,
like you’d use to cook eggs or fish, but above 500 degrees Fahrenheit,
it starts to degrade, and heating it further releases fumes
that can make you feel sick. An empty pan can reach 500 degrees fast
over high heat, but most kitchens are ventilated
well enough to dissipate the fumes. People used to also think
that accidentally consuming PTFE that flaked off a scratched pan
was bad for you, but the current consensus
is that it’s harmless. Because PTFE doesn’t interact with other
chemicals very well, it isn’t thought to break down
inside your body. Whether it’s safe to manufacture Teflon
is another story. DuPont and its spin-off company Chemours now face lawsuits
worth millions of dollars. They’ve been accused of polluting
the environment for decades and exposing employees
and local communities to health risks associated
with a toxic chemical called PFOA. That chemical was involved
in manufacturing Teflon. As for John Gotti, in 1992, the Mob boss was finally
convicted of five counts of murder, among other charges. That prompted the head of the FBI office
in New York City to announce, “The Teflon is gone. The don is covered in Velcro,
and all the charges stuck.”

    Did you know flourine is is actually having an affair? Flourine sucks away everyone’s electrons because it has the greatest coefficient, it’s why flourine and carbon bind so tightly. This is why Teflon creates a lot of static electricity, because it takes your electrons and positively charges your skin, this means when you go to grab say a metal doorknob the protons are repelled and move to the other side while the electrons are drawn to you and this movement is known as static electricity. See the movement of electrons is electricity and because the metal is conductive it can shock you even more than a simple touch.

    Teflon has been proven to be present in the bloodstream of every human on Earth, its a pervasive compound….anytime a compound is created its virtually indestructible (such as teflon) but that just means it binds with organic elements more easily and creates mutations. This is why the human race has developed so many baffling cancers, ulcers, afflictions and lifelong diseases. We are constantly combinging elements to make compounds not naturally found in nature and as our bioligical bodies attempt to respond they ultimately develop cancers, ulcers, illnesses, disease, and deficiencies that are slowly degrading and killing off our human race.

    The electronegativity difference between carbon and flourine is 1.43 (google), which makes it a polar covalent bond. This means that the flourines that surround the carbons are relatively negative. Couldn't other polar substances be attracted to this? For example the positive side of water might get attracted to the relative negative charge of the flourine?

    Although she mentioned that it's harmless but it's no secret now that over time, teflon enters our body with food and is a carcinogen.
    It was also mentioned in an article that 3M knew since 1980's that Teflon is a carcinogen but they sold the utensils anyway.
