Here comes the “superhero” of the plastic Technology world.

“Nature” magazine recently announced a result that was considered “impossible”

Scientists at MIT have developed an entirely new material, called 2DPA-1, which is 4-6 times stronger than bulletproof glass and twice as hard as steel, but only 1/6 as dense.

Most surprisingly, it’s only as light as regular plastic.

That is, it is extremely strong and extremely thin.

Also, it’s easy to mass-produce.

This also means that this “super plastic” is very close to everyone.

The revolutionary progress of materials science is a subversive change for all walks of life. Naturally, it also covers all aspects of our lives.

Let the “super plastic” fly for a while

when it’s on the phone

As a lightweight and durable coating, it makes your phone more resistant to wear and tear.

when it becomes an everyday tool

The plastic bags we usually use can be made into more zippered bags and reused, and they are more durable than cloth bags and leather bags.

When packing some specific items, don’t worry about the plastic bag being punctured casually.

when it’s used in a car

As a material for making cars, it can make cars lighter, which in turn reduces energy consumption and lasts longer.

As a barrier coating, it protects the metal or steel structure in a car, giving it a longer lifespan.

Because its density is so low that it is impermeable to gases, this barrier coating can also be turned into a “paint” or industrial coating that can be applied to items in the home that need it, preventing them from oxidizing, rusting, and rotting.

like a natural barrier.

This will be its first and most immediate commercial application.

when it is used on a building

The performance of this “super plastic” is better than that of steel and other materials. Whether it is building bridges or buildings, it can reduce the use of materials compared to the past.

At the same time, making this material is simpler than making both glass and steel, which reduces energy consumption and labor costs.

In other words, it is more environmentally friendly and sustainable.

For all walks of life

It can be turned into a shield and a body armor, which can make the police travel easier and safer; in aerospace equipment, it can also reduce the weight and ensure the launch quality…

It is conceivable that its powerful features will also be used in more places for our necessities of life.

How is “super plastic” made?

The “superplastic” 2DPA-1 is a two-dimensional polymer.

Until now, polymers have usually only been able to form one-dimensional structures.

Our everyday plastics, rubbers, and glass are all polymers. They are essentially single molecular chains that are connected together flat like spaghetti. When new molecules are added to their ends, they grow and expand like a cake in an oven. , and then into a three-dimensional object.

This allows them to be very light, but also exposes a weak point. There are gaps between the molecules, so the gas can pass through, so it is not rigid enough.

That’s why when you put a bag of spicy strips in a plastic bag, you can smell the tempting smell from the outside too.

Scientists have been trying to study two-dimensional polymers for decades, but have failed.

Because as long as there is a single monomer that does not move according to the rules and starts to deviate from the left and right to rotate, the flaky structure will be destroyed, and finally it will expand into a “fluffy cake”.

This time, MIT Professor Michael S. Strano and his colleagues have finally pushed the envelope.

They created the new material with a compound: melamine.

Melamine has a structure of carbon and nitrogen rings, and the monomers can grow in two dimensions to form disks, which are stacked on top of each other. The hydrogen bonds between the layers are stably connected, and the structure becomes very strong.

It’s like all the children sitting in a row on the playground, holding hands, then leaning against each other, and locked together like Lego blocks, and can’t be separated again.

Thus, new two-dimensional polymers were born.

This high-strength material is not only very light, but also very hard, harder than steel.

Because the monomers are firmly locked together, neither gas nor water molecules can penetrate, and the airtightness is very strong, which is why it acts as a natural barrier and is airtight.

What’s even more surprising is that these polymers assemble on their own.

Only a solution is needed, in which the monomers can stack themselves into sheets, and one can directly add materials to easily synthesize more composite materials.

So, it can be mass-produced.

Now, researchers are already working on new applications for coatings and membranes, and when further research is done on structural adjustments, a new generation of polymers for nanofiltration and gas separation can be produced.

The future applications of “super plastics” are limitless.

What kind of “future plastic” are we waiting for?

Now, everyone’s impression of plastic may not be very good.

Plastic straws inserted in the nostrils of sea turtles, plastic garbage that cannot be degraded for hundreds of years, plastic products that cannot be recycled and can only be reused with difficulty, the waste gas generated by burning plastic…

There is data showing that:

If the life cycle of plastics were a country, it would be the fifth largest emitter of greenhouse gases in the world;

According to data released by the United Nations, the world consumes 500 billion plastic bags every year, and 1 million plastic bottles are sold every minute;

If we don’t adjust the way we produce and use plastic, the planet will have 12 billion tons of plastic waste in 2050.

Therefore, from Coca-Cola, the largest plastic polluting company, to increase the recycling of plastics, to various new consumer brands that advocate green environmental protection, the supply chain and products are more sustainable, and even major supermarkets and convenience stores have begun to “Plastic limit”.

But the reason why plastic is so hard to get rid of is because it really works so well.

Therefore, it is necessary to solve the problem from the source.

There are already many companies replacing plastics with new materials.

Startup Ecovative uses mushrooms as packaging material, in which mycelium can grow to a specific size and shape, and also facilitates degradation and recycling.

Allbirds, which has always emphasized environmental protection, uses cashmere for shoes, recycled bottles for shoelaces, and the packaging has also been replaced by 90% recycled cardboard.

At the half-marathon held in London the previous year, athletes ate a “water polo capsule” called “Ooho” halfway, because the packaging was not plastic, but made of seaweed and plant ingredients.

There are even people who dissolve the DNA strands of salmon sperm in water to form a soft, stretchable “hydrogel” that the team calls “DNA plastic.”

“Plastic substitutes” are a way to ease, but there are many places where real plastics cannot be replaced.

So on another track, new plastics were born one after another.

Everyone is more familiar with the current biodegradable plastics.

“Biodegradable” plastic, in terms of terms, is generally understood as throwing plastic in the ground, and it will disappear automatically after a while.

But in reality, it still needs enough time to degrade, possibly hundreds of years.

This doesn’t really make much sense, after all, everything is biodegradable for a certain period of time.

Biodegradable plastic.

There is also “compostable plastic”, which you may think will disappear in the soil and make the soil just nutritious.

But actually, it only works in special composters. And even if this plastic is readily available, we can’t throw it all in the right soil.

Technology is advancing rapidly.

Last year, also in the journal Nature, scientists have created plastics that degrade in days or weeks.

A startup in the San Francisco Bay Area has also created “compostable plastic” called Intropic Materials, which allows people to pot plants and turn them into fertilizers at home.

Once these plastics become widespread, we can throw them away without guilt.

The aforementioned “super plastics” can be applied to more new fields and even replace steel and other materials.

It takes a little time and practice to make existing plastics be recycled and digested, and make future plastics come faster and more effective.

This plastic war has only just begun.
