This plastic is called 2DPA-1 and is twice as strong as steel
Metal, especially steel, is one of the most durable and strongest materials, and it is widely used across many industries. However, scientists have been working on creating other materials that can offer the same strength as steel, or even more. One such material is plastic.
A group of scientists at MIT has created a plastic that is twice as strong as steel. This plastic is called 2DPA-1. It is a two-dimensional polymer that self-assembles into sheets, unlike other polymers, which form one-dimensional, spaghetti-like chains. The 2DPA-1 arranges its polymers as flat discs that are linked to one another with the strongest molecule-to-molecule bond in nature: the hydrogen bond.
The 2DPA-1 plastic is also impermeable to gases. While other polymers are made from coiled chains with gaps that allow gases to seep through, 2DPA-1 is made from monomers that lock together, leaving no space for molecules to pass through. This gas-blocking property makes it a very good barrier or coating, which can be used to protect metal in cars and other vehicles, or steel structures.
The 2DPA-1 plastic can be manufactured in large quantities, and it is relatively practical to produce. The process starts with a monomer, such as melamine, to which some chemical solvents are added to make thin sheets of 2DPA-1. These sheets can be stacked to make ultra-light and strong building materials. The plastic can also be rolled up into tiny tubes and mixed into other plastics to make composites like carbon fiber.
