Polymer

In wastewater produced by the textile industry and others, dye is one of the primary pollutants. A newly developed synthetic polymer is capable of removing that dye from the water, plus it can be cleaned up and reused to treat more wastewater.

Finding a scratch on your car is a special kind of heartbreak, but in the future they might be gone before you even notice. Scientists in Korea have developed a coating that self-heals scratches in as little as 30 minutes when exposed to sunlight.

Construction is one of the largest sources of greenhouse gas emissions. Flinders University researchers have now developed a polymer made out of industrial waste that can be formed into building bricks that bond together without needing any mortar.

Industrial piping has a hard life, as it's constantly exposed to liquids that can damage its inner surface over time. A new polymer coating could help protect such pipes, while removing toxic metals from the liquids as it does so.

When it comes to plant-based materials, many people may picture something that's "green" but not very robust. Such is not the case with a new MIT-designed composite, however, which is claimed to be as hard as aluminum and as tough as bone.

Engineers at MIT have developed a new ultrathin material as light as plastic but stronger than steel. The durable material could be used in vehicles or electronics, and makes use of a manufacturing technique that was previously thought impossible.

Although carbon fiber can be repaired and recycled to a certain extent, it's typically just discarded once damaged. According to a recent study, however, a new type of the material can be easily fixed or reused through the simple application of heat.

As we increasingly move toward renewable energy sources like wind turbines, we're going to require the best means possible of relaying electricity from them to our cities. A new cable-insulating material may allow us to do so much more efficiently.

There are now a number of materials designed to give robots or prostheses a sense of touch. And while most of them are thin and skin-like, a new alternative takes the form of a spongey foam – and it combines several desirable qualities.

When producing "smart fabrics" made of conductive fibers, it can be difficult placing functional elements such as electrodes in specific locations along those fibers. A new polymer, however, could make doing so much easier.

Ordinarily, when using an off-the-shelf 3D printer, it's quite difficult to print a single object that incorporates multiple materials. An experimental new system could make it easier, though, by utilizing a "programmable filament."

Researchers have developed a new type of fabric that keeps the wearer much cooler. Made from different polymers in a relatively simple way, it can efficiently transfer heat and wick away sweat, while remaining water repellent from the outside.
