Scientists have created plastic equivalent to steel — strong but not heavy.Plastics, which chemists sometimes call polymers, are a class of long-chain molecules made up of short repeating units called monomers.Unlike previous polymers of the same strength, the new material only comes in membrane form.It is also 50 times more airtight than the most impermeable plastic on the market.Another notable aspect of this polymer is its Simplicitas synthesis.The processus, quod fit locus temperatus, requirit solum cheap materiae, et Polymer potest esse molem, produci in magna laminas quae sunt tantum nanometers dens.the inquisitores fama eorum Inventiones Februarii II in Journal Natura.
The material in question is called a polyamide, a threaded network of amide molecular units (amides are nitrogen chemical groups attached to oxygen-bonded carbon atoms).Such polymers include Kevlar, a fiber used to make bulletproof vests, and Nomex, a fire-resistant fabric.Like Kevlar, the polyamide molecules in the new material are linked to each other by Hydrogenium vincula totam longitudinem catenis quae auget altiore vires materiae.
"Et inhaero unum sicut velcro," dixit plumbum author Michael Strano, mit eget engineer.Tearing materiae requirit non solum frangens singulos mocecular vincula, sed etiam super giant bundone.
In addition, novum Polymers potest statim formare fickes.This facit material facile ad processum, ut possit fieri in tenuis films vel usus est ut tenuis-film superficiem in tres partes, seu saepe in triplici in tria, aut in tres ad formare nanosheets
"Potest aggregatum in fragmen chartam? Hoc vertit ex, in pluribus, non potestis facere usque ad opus," Strano dixit. "Ita, invenimus novum mechanism." In hac recens opus, in quadrigis vicerunt crate ad hoc duo dimensiva aggregationem fieri potest.
The reason polyaramides have a planar structure is that polymer synthesis involves a mechanism called autocatalytic templating: as the polymer lengthens and sticks to the monomer building blocks, the growing polymer network induces subsequent monomers to only Combine in the right direction to strengthen the union of the two.dimensional structure.The researchers demonstrated that they could easily coat the polymer In solution onto wafers ad partum inch-laminates minus quam IV nanometers dens.That fere unum-decies crassitudine iusto officium paper.
To quantify the mechanical properties of the polymer material, the researchers measured the force required to poke holes in a suspended sheet of material with a fine needle.This polyamide is indeed stiffer than traditional polymers like nylon, the fabric used to make parachutes.Remarkably, it takes twice as much force to unscrew this super-strong polyamide as steel of the same thickness.According to Strano, Substantia potest esse in tutela coating in metallum superficiebus, ut currus veneers, aut sicut filter ad purificare water.in hoc munus, quod pulchrum filter membrana necessitatibus sine stillans parva, ad nocumentum contaminants in nostra ultima, sed potentiori - est perfecta contaminants in nostra ultima - perfectum contaminants in nostra ultima - perfectum contaminants in nostrae ultima - perfectum contaminants in nostrae ultima - perfectum contaminants in nostrae ultima - est perfectus contaminants in nostra ultima, sed potior est ad otium.
In futuro, Strano spes extend ad polymerization modum diversis polymeros quam Kevlares Analog. "Polymers in circuitu nos," dixit. "Et omnia." Imagine turning many different kinds of polymers, even exotic ones that can conduct electricity or light, into thin films that can cover a variety of surfaces, he adds.”Because of this new mechanism, maybe other kinds of polymers can now be used,” Stano said.
In mundum circumdederunt a plastics, societas habet rationem excitari de alia polymer cuius mechanica proprietatibus sunt aliquid, sed Ordinarius, Strano said.This Aramid est a Sustainability, quod est nobis super-fortis ad cibi a plastic in dexteram, quod est in mundum de Polymer est a gradum ad liberum mundum de Polymer, quod est ad nos, quod super-fortis in a plastic et in paucioribus, quod est in mundum de Polymer est in dextra ad liberum mundum de Polymer, cum a Pads ad Fortem 2D Polymer est a step in dextra ad liberum mundum de Polymer est a gradum ad liberum mundum de plastic.
